Gehr Plastics is ISO 9001 and ISO 14001 approved and certified, guaranteeing a consistently high quality product. The product line that Gehr Plastics produces is also quite large. The materials include: ABS, Acetal (POM-C and POM-H), HDPE, Kynar, Noryl, Nylon, PEEK, PEI, Polypropylene, Polysulfone, PPO, PVC (Type 1, Type 2 and CPVC), PVDF and Ultem materials. All of these materials are available in a wide range of sizes, and yes, some of the largest.

Gehr Plastics Long History

Gehr Plastics has been leading the industry in innovation since 1932, and is now in the third generation of family owned and operation. From the wide range of materials to the extremes in size range, this is cutting edge performance from a family run company. They also released a web-app for picking plastic materials, Gehr Plastic Selection Tool, and it is also available for mobile devices. This comparison tool compares not only plastics, but metals as well, for a great look at the best physical properties for an application.

While quality and size are keystones to excellence, Gehr Plastics is also interested in materials that the rest of the industry has not considered. Over the last several years, Gehr has produced some PLA materials (made from plants) and even a Clear Nylon Rod for higher temperature sight-glass applications. These are just a few of the cutting edge areas that Gehr Plastics is leading in this industry.

Industrial Plastics is Master Distributor

Gehr Plastics materials are sold through a tight network of Master Distributors throughout the United States. Industrial Plastic Supply, Inc. of Anaheim, CA is proud to be one of the top selected suppliers of these innovative materials.

Best Tools To Assist In Your Plastic Sheet Search

Use the best available tools to narrow down the best plastic sheet material for your application.

What are the best methods to pick the proper plastic sheet material?
Use the tools that the professionals use to find the best plastic material for your application.

Where To Begin

The process of picking the proper plastic material starts with determining the ‘must have’ physical properties needed for your application. Designing a part with the minimum performance factors in mind will help to eliminate an overly
expensive part.

Critical factors to consider are:

  • Temperature requirements (short term and long term)
  • Chemical or Environmental Requirements
  • UV resistance (Will it be in direct sunlight)
  • Color or Transparency
  • Strengths (Impact and Compression)
  • Compliance Issues (Certification for FDA, NSF, Dairy, etc.)

Review The Plastic Property Comparison Guide

The first tool suggested is a chart produced by the IAPD (International Association of Plastic Distribution – http://iapd.org/) linked in picture below, and listed on this chart are the most common plastic sheet and plastic rod materials that are commonly available. In addition, the chart compares the physical properties of these common plastic materials. Click on picture to access chart.

IAPD Plastic Selection Rectangle Chart
Included in this chart is a relative cost comparison, which will assist in limiting the materials to proper plastics for a application without over-designing and using an expensive ‘over kill’ material. Some common plastic sheet materials can be very expensive. Materials like PEEK (Polyetheretherketone) can be in the $100 per pound range or more.

Start Search With Temperature Resistance

After looking over the IAPD Physical Properties Chart, now it is time to evaluate specifics for your application. The critical factors listed above are ranked by most important to least important. If your part needs to handle a continuous temperature of 300 degrees F, this is a critical physical property. Picking a material that softens at 250 degrees is a
recipe for disaster. Pick a material that can handle the temperature first.

Will Part Have Chemical Exposure

Next, look at environmental requirements. Parts exposed to chemicals are important to research. Find the chemical make up and the concentration of the chemical to insure the material you pick can handle this solution. Many plastics have excellent chemical resistance as evidenced by evaluating the container the chemicals are stored in already. A common plastic that is chemical resistant is Polypropylene, the same material used for automotive batteries. While Polypropylene and HDPE sheets are excellent in chemical resistance, their temperature range is quite limited. Also, these two plastics can not be easily bonded or glued, and would require heat welding for assembly.

Does Your Part Live In The Sun

Most plastics do not handle long exposure to direct sunlight without an additional UV additive. The one exception is Acrylic, which is the most UV resistant plastic sheet available. Some plastics handle UV well if they have a carbon black additive, or a extra UV package added at time of production.

How Critical Is The Color

The most common colors in many plastic sheets are Natural (white to tan) and Black. While other colors are available with a special run, this may require a large minimum order. Some plastics, like HDPE are available in many colors and textures for use in marine, playground and food processing applications. In many plastic applications, a machined part is being made, and the color is the least important factor. If it is an internal part of a machine, no one really cares about the color of the part. Some clients look for materials in a specific color to help ‘brand’ their parts for easy replacement and identification.

How Much Stress Will The Part See

Strength is a wide range of physical properties covering many stresses a part may be exposed to. From impact to compression, expansion to tensile strength, all of these can be critical in designing a plastic part. There are other factors in the ‘Strength’ realm, like Notched Izod and Stress Can Cause Your Plastic Part to Bow, Twist and Crackwater absorption. If your part will be exposed to crushing pressure, pulling apart force or impact, these are critical things to consider prior to picking your plastic part.

PTFE is a soft and slippery plastic, but will ‘cold flow’ under high pressure, and High Pressure Laminates like G-10 FR 4 sheet can withstand some of the highest pressures. The Notched Izod tests for materials that break easily if a scored mark has been made in the surface. Acrylics break very easily if scored, but UHMW will not break at all under the same test.

What Agency Approval May Be Required

In many applications a part may require approval or testing to meet a third party certification. One such common application is for materials in food processing applications. Common requests included UL ratings, Fire Ratings, Military specifications and many more. Food contact is a popular request, coving material that is either FDA (Food and Drug Administration) or NSF (National UL Ratings for Plastic MaterialsSanitation Foundation) approved. These agencies insure that materials are rigorously tested and comply with their requirements for safety. Some common materials used in food processing that meet the FDA certification are Delrin – Acetal, HDPE, UHMW and Nylon, plus many others.
Once these steps have been completed, several materials should present themselves as meeting your criteria and physical property requirement. Unfortunately there is no one perfect plastic that works in all applications. However, for almost every application, there is a material that will work, and work better than most other substrates.

Cool Online Tool

There is also an additional tool that can be used to help identify some of these properties quickly, the Gehr Plastic Selector online application.

If you are still in need of assistance in identifying an appropriate plastic material, contact an experienced Plasticologist at Industrial Plastic Supply, Inc. – call 866-832-9315

From Plywood To Polycarbonate Sheet

People in the plastics industry have known for over 50 years that Polycarbonate Sheets are tough. This clear plastic sheet material is commonly used to replace window glazing. The best known property for this sheet materials is that it is break resistant, or in many cases, unbreakable. This is a great benefit for areas where window glass is broken easily.

Recently some cities have passed ordinances to change out the plywood window coverings on abandoned homes, and they are installing clear polycarbonate sheets instead. This is a very attractive replacement, and is a big step in fighting the blight of abandoned homes.

Polycarbonate is produced under several trade names, including Covestro Makrolon®, SABIC Lexan®, Cyrolon®, Zelux®, Tuffak® and many more. These materials are available in sheets, plate, slab, bar and rod.

Read more on this material below.

Cities moving from Plywood to Polycarbonate Sheet Protection for abandoned homes

Excerpt from AZCentral, The Arizona Republic:

Property owners and banks in Phoenix had begun outfitting windows with sheets of polycarbonate, a thin, nearly indestructible plastic that mirrors the appearance of glass.

And last month, the city became among the first in the U.S. to make polycarbonate windows a matter of municipal law.

Phoenix now requires all window and door openings visible from the street to be secured with the material if the structure has been unoccupied for more than 90 days. The 90-day provision is also new, replacing the previous deadline of 180 days. The measures were the result of an abandoned buildings task force that Gallego spearheaded.

Read the rest of the story, and see Phoenix City Councilman Michael Nowakowski and City Manager Ed Zuercher attempt to break a polycarbonate window in Phoenix: http://www.azcentral.com/story/news/local/phoenix/2015/04/02/phoenix-fights-blight-plastic-windows/70826784/

Durham County, North Carolina also made a change:

By Taylor Knopf, tknopf@newsobserver.com

No one likes living next to abandoned buildings with boarded up doors or windows. So the city of Durham started replacing the plywood eyesores with a clear, durable plastic.

The city is working to reduce the number of abandoned houses by helping owners fix them up. But for houses that still need boarding up, the city has found that plastic not only improves the overall appearance of a neighborhood, it may reduce crime by discouraging squatters and making it easier for police to see inside vacant buildings.

“I can’t stress enough how the elimination of the boards has a tremendous positive impact on neighborhoods and communities,” said Faith Gardner, housing code administrator of the city’s department of neighborhood improvement services.

These communities have fought back against vandalism and crime, as well as enhanced the value of local homes by changing from Plywood to Clear Polycarbonate Sheets. This super tough Bullet resistant Polycarbonate Sheetglazing grade clear Polycarbonate Sheet material is the same kind of material that Police Officers use for face shields and banks are using for bullet resistant glazing.

The premier manufacturer of Polycarbonate Sheet in the USA is Covestro (formerly Bayer MaterialScience), and they produce Makrolon Polycarbonate Sheet. Polycarbonate is also available in rod and thick plate for machined parts.

Consider using Polycarbonate sheet for your next glazing material.

Why Plastic Materials Are Unfairly Blamed

Plastics have been around for over a century now, and are used in almost every industry and application. The problem is that society has made the plastics industry the poster child for waste, trash and pollution. This is unfair, and factually incorrect.

Plastic materials are lighter, cost less to produce, use less electrical power to produce, and are safer for use. It is not new phenomenon that a material or product, once used, gets thrown away. This is the normal life cycle of many materials. Some inexpensive plastic materials used in consumer goods are made to throw away once the item has been purchased. Things like the indestructible packing we fight on kids toys, the cheap plastic sporks from restaurants, the prolific plastic water bottles and of course, the plastic grocery bags. All of these materials are 100% recyclable, the hitch is that it requires a little effort to recycle.

Are Plastic Materials The Cause?

On the positive side, the products that plastic currently replaces are much larger, heavier and generally cost more to produce, and use more energy to produce. This means, that the large amount of plastics that are not being properly disposed of, are replacing much larger quantities of materials that would not be recycled. I still remember times when I was a kid, and seeing tin cans in the lakes and rivers when out fishing. People polluting with their trash is not a new thing, now it is just a different group of materials.

Thermoplastic plastic materials are recyclable, and can be used over and over again. Generally, the recycled product would not be for a Food or Medical application. A common use of recycled plastic is with the collected milk jugs and detergent bottles, both HDPE, can be ground and turned into plastic lumber. The plastic lumber can be used to replace standard wood products for decks and outdoor furniture, and it will last for 15 – 20 years with no maintenance or painting. The cost savings and reduced use of natural resources for this one product can be staggering. The color doesn’t fade, it wood won’t split or crack, and it continues to look good for up to two decades.

Our recent article, “Plastic Material Bad Reputation – How did we get here?“, we discuss the factors that have lead to the ‘throw away’ society that we have become. Much of this bad reputation is for products that are designed as one use and then designed to be thrown away. So, if we are to change the bad reputation, companies need to change this design flaw, and start using materials for applications that can be reused easily.

If we can minimize the use of throw away plastics, and recycle the plastic material once we are done with it, we can help to limit plastic in land fills.plastic materials don't pollute, people pollute.

The blame for plastic pollution should be placed…on people. The plastic is not the cause of the problem, it is the litter-bug and irresponsible individuals that trash our planet. How do the plastic bottles and grocery bags end up in the ocean. They certainly don’t throw themselves in to the ocean, it is lack of responsibility and negligent behavior.

It really only takes a couple of seconds to throw something into a recycle bin. Even better would be to reuse the plastic bottles or plastic bags. Plastic materials are not the problem, empathetic people are the problem.

Plastic Mentor – Focusing on Plastic Sheet Material Education

We have been working very hard over the last few months to bring you new, informative, and hopefully interesting articles on plastics.  However, even though we focused on writing articles pertaining to plastic—we have also covered other topics as well, like protecting yourselves from hackers, B2B Live Online Chats, Domain Names Available, The Next Innovation in Sound Technology and even an online prank!

The purpose of the Plastic Mentor blog is to educate all those people that are interested and willing to learn something new. Curious ones that don’t stereotype plastic under one category and are intrigued to know about what they are buying.

Why Choose Plastic Sheet?

The truth about plastic in general is that it is versatile and efficient. It can cut the cost of production and in most cases produces less green house emissions than paper, metal or glass.  

Choosing the proper plastics can be accomplished by narrowing down some basic properties. For example, is the application going to be used for indoor or outdoor use?  What temperature will this plastic be required to resist? Is the plastic clear or colored? Are you looking for sheet, slab, rod or tubing? What are the dimensions of your part? And finally, how many pieces are you looking to get?  These might seem like tedious questions, but they are essential to get you the best plastic for your application.

Our Newest Addition Asks A Great Question

When a recent new employee started working at Industrial Plastic Supply, they asked the General Manager, “Which material is the best plastic?” 

At first the GM just chuckled politely, but then graciously gave a good analogy.  He said, “Asking what the best plastic out there is like asking a car salesman what is the best car on the market?  It certainly depends…a fast 2 seat sports car is probably not the right transportation for someone looking for a new family vehicle.”

This is very insightful, and most people never think about plastic in this way!

Plastic Sheet and Rod Questions Welcomed…

When you come to Industrial Plastic Supply, please ask questions…it helps us just as it helps you to get you. Please contact us for help in identifying your next plastic material.

PTFE Sheet versus UHMW SheetsUHMW sheet compared with PTFE sheet Thread Seal Tape

UHMW (Ultra High Molecular Weight Polyethylene) and PTFE Sheet (PolyTetraFlouroEthylene) are very similar materials, and yet very different at the same time. They both possess certain characteristics that make them similar to each other. For instance, they both have a very low co-efficient of friction, which means they are great for sliding applications and are easy to machine.

Both of these materials are very resistant to chemicals such as chlorine and some acids and have great wear resistance. They have low to no water absorption. They also are FDA approved for handling food. PTFE and UHMW Polyethylene are both nearly impossible to bond (without treatment) and are susceptible to sagging under tensile load which is called ‘creep’. These both have very low coefficient of friction and work well for wear strips, slide pads and truck liners to make it easy to empty. These two materials are different in many ways also, and choosing between the two materials for a specific job is critical.

Below are a few examples of how these two materials are different.

1. UHMW is a polyolefin and PTFE is a fluoropolymer. Polyolefins are double bonded carbon while Fluoropolymers are carbon and fluorine bonded. UHMW is a monomer which is consisted of one atom that will bond with another to form a polymer. PTFE is a polymer which is made up of a repeating chain of monomers.UHMW Ultra High Molecular Weight Polyethylene Truck Lining

2. PTFE has a higher temperature range than UHMW. The PTFE has a continuous use temperature of 500 degrees F. UHMW is much lower with a continuous use temperature of 200 degrees F and a melting point of 271 degrees F. The UHMW starts to become become soft at higher temperatures while the PTFE is much more resistant and with a melting point of 621 degrees F.

3. UHMW has higher abrasion resistance than PTFE. Both have great impact and wear resistance but because of UHMW having a molecular weight between 2-6 million making it the best wear resistance material in the plastic family, it makes it ideal to take wear and impact over a wider range and longer period of time without losing its properties.

4. UHMW has a much lower density than PTFE. This makes UHMW able to float in water while Fluoropolymers are significantly heavier (almost twice the density of UHMW) and would sink.

5. PTFE has excellent electrical and thermal properties. The virgin grade of PTFE is a better insulator and exhibits better electrical properties which can be used in radio frequencies, cables and circuit boards while UHMW cannot.

6. UHMW is much less expensive than the Fluoropolymers. Especially recently, PTFE has become harder to come by, and during the last 18 months there has been a global shortage of a key raw material called fluorspar that is used to make all Fluoropolymer materials. The ability to take lots of wear and tear and requiring low long term maintenance makes UHMW more cost effective.

7. The standard color of PTFE is Natural, which is a dense white. The UHMW comes in Natural (a deep milky white) or Black. The UHMW can be produced in many colors, and minimums are rather low. To obtain PTFE in colors is much more difficult, and would also have large minimum orders.

These are just some examples of plastic materials being similar, and yet having very different properties. The PTFE Sheet and UHMW Sheet may appear very similar in color and can be used for some of the same applications, but when needed for a specific use or property needed, one might be dramatically better than the other. As the old saying goes, “You should never judge a book by its cover” and the same is true with plastic. Review the properties and test prior to choosing a final material for your application.

Plastic Strip is common in other materialsPlastic Strip, plastic Strips and Plastic Tapes, Plastic Bar

A common standard item in the metals industry is ‘strip’. Strip is normally a piece of material that is 1/16″ – 3/8″ thick and 1.0″ – 4.0″ wide, although thicker and wider materials can also be referred to as strip. The metals industry produces various metals in these sizes of strip. In the plastics industry, strip is something we cut from larger sheets. The sizes are the same as listed above, but are cut from 48″ X 96″ or 48″ X 120″ sheets.

The a few of the most common plastics materials we cut to plastic strips are:

HDPE (High Density Polyethylene)

PTFE, TFE (Polytetrafluoroethylene)

UHMW – Ultra High Molecular Weight Polyethylene

Acetal / Delrin

Nylon – Polyamide

PVC – Polyvinylchloride

Polycarbonate – Covestro (Bayer) Makrolon

Most plastics can be cut to these strip sizes, with various lengths available depending on type of material. In some materials and in some sizes, depending on quantity, special run to size plastic strip is available. These special run plastic strips can be run to almost any length. Specifically, in the UHMW and PTFE materials, much longer lengths are available in rolls of material. The UHMW can be purchased in standard and adhesive back varieties. This UHMW with adhesive is a commonly used item in the wear strip applications because of its ease of installation. A large market for this kind of strip is in the food processing industry for all wear points and to reduce noise in the plant. Some of these same sizes with adhesive on the back are available in the PTFE, and are available in long tape style rolls. In some cases, colors other than natural are available, contact us for details. Plastic Strip, plastic bar, excellent in food processing and material handling

Plastic Strip and Strips are available in special sizes

With the massive range of plastics available, and most of these materials available to be cut to strips, the nearly unlimited amount of choices in plastic strip availability make this post difficult to be all inclusive. Great material for the industrial, food processing, material handling, automotive and recreational industries.

Most plastics are available in large sheets, and we can cut these sheets to strip for you. Also, depending on the material, size and quantity, we can custom extrude your strip in longer lengths and to your requirements. Decide on a type of plastic, determine the size and quantity, and give us a call. Use your imagination, we can help.

If you have a project where strips would be ideal, please contact us to see if the type of material you need is available in the strip configuration that would be beneficial. Call us at: 866-832-9315 or drop us an email and we will be happy to go to work on your requirement.

Is HDPE Sheet and Acetal Sheet (Delrin) the same?

Here is another popular question asked by our clients. Is HDPE the same as Acetal / Delrin?
No, they are two totally different materials. Although the natural color of both is a milky white to opaque white, and they do look a bit similar, they are not. (HDPE is milky white to almost translucent depending on thickness, and Acetal is a more opaque white to slightly milky – once again depending on thickness . See picture below of .500″ thick samples of HDPE and Acetal sheets)

HDPE and Acetal – Some DifferencesHDPE sheet and Acetal sheet Natural Color Samples Both .500" thick sheet

The HDPE sheet and rod is a softer material, and is commonly known for its FDA certification and used in numerous food applications, such as: one gallon milk jugs, cutting boards, colored water glasses/cups, and many, many more. While it can be machined, because it is a bit softer and lighter, the tolerances it can be machined to are not very tight. It is not bondable, so it makes a great non-stick surface for sticky foods and adhesives.


The Acetal / Delrin also have FDA certification, and are used heavily in the food processing industry. This material is a more mechanical material and is used in bearing and wear applications, cams, feeder screws, etc. This material is can be machined to tight tolerances, and will wear for long periods without lubrication. Due to its exceptional wear properties, it is not bondable, thus requiring mechanical fastening or threads to assemble. It has a very low water absorption, and you will find it in your toilet tank as the white moving parts in the filler mechanism. It is an extremely popular material for machinists, as it works much like soft brass.


While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently.

While both materials are FDA approved, are machinable and can be used to make rigid wear resistant parts, they are two different resins and have drastically different physical properties. Another major difference is in the weight of these items, HDPE sheet and rod material weighs about 35% less than the Acetal sheet and rod material. Please check the data sheets for more information to assist in proper material selection. Acetal Data Sheet and HDPE Sheet Data

Acetal is commonly known as: Delrin, Ensital, Unital, Pomalux, Ultraform and many more.

HDPE is also known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.

Things you should know about Polycarbonate Sheet, Sheets and Panels

A common misconception is that ‘all polycarbonate sheets are the same’. This is not true, as a matter of fact, it is far from a fact. While most manufacturers of polycarbonate sheets start with a similar base resin, this is where the similarities normally stop. Most polycarbonate sheet extruders run a base material far different from what the standard has been for the last 30 years. Most polycarbonate sheet is now made without the flame rating it had in the past. Polycarbonate Sheets are sometimes called ‘polycarbonate panels’ or ‘polycarbonate plates’, they are still made from the same high quality resins. One of the best known manufacturers of Polycarbonate resins and sheets is Sabic Polymers®, the manufacturers of Lexan® resin and Lexan® Sheet products. Over the last several years, Sabic has quietly discontinued the UL ratings on their Polycarbonate.

Industrial Plastic Supply And Makrolon GPBayer MaterialScience now Covestro

For more than 30 years, Industrial Plastic Supply has relied on the high quality Polycarbonate Sheets produced by Sheffield, now part of Covestro (formerly Bayer MaterialScience). Covestro produces a crystal clear, ultra high impact strength resin, this Makrolon resin is the finest in the industry. Covestro has also chosen to continue to produce this high quality material with the UL 94 V-0 rating, the only supplier to continue this expensive, but extremely valuable service. Take a moment and look at your requirements, see if perhaps somewhere on the blue print is a note that states your polycarbonate material needs to be UL 94 V-0 approved or rated. If so, Makrolon GP is your only and best choice!

How is Covestro Makrolon Polycarbonate available

We stock Covestro (Bayer MaterialScience) Makrolon GP in flat panels, considered Polycarbonate Sheet or as Polycarbonate Sheets. We can cut theses sheet Polycarbonate materials to strip or strips, blocks, or just a cut to size piece. At Industrial Plastic Supply we have stocked large quantities of these materials, and continue to keep Makrolon GP and Makrolon FI sheets in stock. With a wide range of thicknesses ( .030″ – .500″ thick) and sheet sizes of 48″ X 96″, 60″ X 60″ and 72″ X 96″ as standard in .118″ – .500″, we can fill all your requirements.Covestro (Bayer) Makrolon GP Polycarbonate Sheets formed into Riot Shields

Why you should use Makrolon Polycarbonate Sheet

Superior clarity, quality, surface finish, flame retardant and full USA factory technical assistance are just a few reasons. Buying polycarbonate sheets imported from somewhere half way around the globe, from an unknown manufacturer with little or no technical support can be very risky.

PVC Sheet and Rods

(Rigid Vinyl and CPVC)

Polyvinyl chloride (PVC) has shown its versatility and durability for decades. Its use in piping, sprinkler systems, the construction industry and other areas has made it a popular commodity. The industrial-grade PVC sheet has numerous applications in the manufacturing area. Its low cost, workability, easy bonding, corrosion and weather resistance make it an all-round choice of industry.

PVC is Easy To Work With

Regardless of the application, working the PVC sheet is easy and cost-effective using simple tools that are common in other applications such as wood and steel. The chemical composition of the PVC sheet makes edging and machining simple and straightforward, and usually makes cooling unnecessary. However, when cooling is needed, compressed air, water or other liquids can quickly cool the material. Industrial PVC can be shaped and formed by:
          • SawsPVC Machined Part PVC Sheet and Sheets, Rigid Vinyl and CPVC Plastic Materials
        • Drills (Hand-held or drill presses)
        • Routers
        • Punch machines
        • Standard CNC Equipment

It is also easily sealed and bonded to itself or using common industrial adhesives. The easy working and bonding of PVC sheeting make it an excellent choice for use in manufacturing and industrial applications. Couple that with its relative low cost and ability to use common tooling methods and PVC is an indispensable choice, and can replace more expensive materials such as: ABS, Acetal, Nylon and many more.

Several PVC Grades Available

PVC is available in several grades. The most common is the Type 1 Gray PVC – the standard commercial grade PVC for machining, bonding and painting. CPVC (Chlorinated Polyvinyl Chloride) is also available, and sometimes called Corzan® or Lam 2000®, and is a higher continuous temperature resistant material. The CPVC is normally a blue tinted clear color, and is also available in a FM4910 approved grade. We also supply the Type 2 PVC which is used for improved impact strength applications. This Type 2 material is available in a White or Light Gray color.

PVC Sheet Comes In Standard Sizing

Storage and transport of PVC is also an advantage. Its 48″ x 96″ size makes it a uniform size with plywood and other building products. The range of thickness is: .062″ – 3″ thick and thicker. There is no need for special storage or handling equipment. Common storage areas that can store drywall, plywood or other standard building materials can easily store these sheets. Forklifts and existing conveyor systems never need retrofits to handle the PVC.

Topic: PVC Sheet and Rod

Nylon Rod and Sheet (Polyamide) Grades available

The Nylon family of plastics are all very tough, strong, machine well, and have excellent wear properties. Nylon is a very popular plastic material, and is found in numerous applications. One of the largest usages is the production of household carpeting because of the excellent wear resistance. Nylon replaces materials such as UHMW, PET, Acetal – Delrin, and ABS. It will outwear most plastics and is self lubricating.

The wide variety of types and colors is one of the largest in the plastic industry.Nylon Rod Type 6/6 and Type 6, rods can be machined into gears

Nylon Type 6/6 Rod, Sheet and Plate

The extruded Nylon 6/6 (Nylon Rod and sheets) material (aka: Polyhexamethylene Adiptimide) is available as Natural (tan – straw), Black, Glass filled (medium tan) and a molybdenum disulphide filled which is very dark gray. The most common size range for the extruded Nylon 6/6 is .125″ – 4.0″ diameter rod, and .125″ – 4.0″ thick sheet. The thicker materials should be cast due to cost and stress issues. For addition details on the Nylon Rod and Sheet 6/6 – see the data sheet.

Nylon Type 6 Cast Polycaprolactam

The cast Nylon type 6 has almost limitless possibilities. Many colors are available in Cast Nylon, the natural color, black, blue, dark gray (normally molybdenum disulphide filled again), green and many more. Sometimes the color is determined by the additive (oil filled) or by industry. Because of its relative ease of manufacture, many companies prefer to get their Nylon in a special color to help ‘brand’ their parts.

Cast Type 6 Polyamide can be made in Nylon rod from about 1.25″ diameter to almost any size. Nylon sheet normally starts at about .75″ thickness, and once again, can be made to almost any thickness. In addition to standard rod and plate, other sizes and shapes can be cast from Nylon Type 6 – ie. discs, tubes, near net shapes, large profiles, etc. The only limitations are how much money you have, and the size of the truck to get it to you! We have had cast very large blocks (11″ X 11″ X 48″ solid), sheaves up to 66″ OD, large tubes 36″OD X 12″ ID X 14″ long, and many more massive Nylon Cast parts.

Nylon 6/12 -Low Moisture Absorption

The claim to fame for the Nylon Type 6/12 is the low moisture absorption of the material. It is more stable that the type 6 or 6/6, and with the lower water absorption, this resin can handle a wider range of environments. Our manufacturer can run this as an Extruded Nylon Rod item or as a Cast Nylon Rod item. This opens the door to a wide range of sizes and shapes. This material exhibits most of the same properties of the Nylon 6/6 and Cast Type 6, with some slight improvements in key properties.

Filled Grades of Nylon

Because of the processing of Cast Nylon, many additives can be mixed into the material. The most common are: glass filled, oil filled, Kevlar fiber filled (Hydlar Z) and the molybdenum disulphide (M0S2). In addition, other fills and colorants (pigments) can be added to assist in manufacture or processing.

Common specifications for Nylon are: L-P-410, ASTM D-4066, L-P-395C, Mil-M-20693B Comp A, Ty I, IA, II and III, Mil-M-20693B Comp B, Ty 4, Mil-P-17091B Type 1, and Mil-P-46060, PA0613, ASTM D-5989 S-PA0511, and more.

Before buying your next big chunk of Nylon, contact us for information on the benefits of a filled  or near netshape Cast Nylon part.

Contact us with your specifications, we look forward to assisting you.

What is the Strongest Plastic – Polycarbonate Sheet?

Many plastics are durable and have good impact strength. Delrin® – Acetal for example is a very durable and strong material, but compared to some other materials the impact strength is lower. The Acetal – Delrin is the best machining plastic around, it is used to make long lasting and good wearing parts for machines. Another great plastic that holds up to wear and tear is UHMW. With its high molecular weight and low friction resistance is ideal to take abuse over long periods of time.

However, one of the strongest materials in the plastic family is Polycarbonate. Commonly Polycarbonate Sheet or Sheets formed into Riot Shieldsreferred to Lexan® (SABIC) or Makrolon® (Bayer) Polycarbonate Sheets. Polycarbonate is by far one of the strongest (highest impact resistant) ­­­­­plastic materials, and is warranted against breakage. With its high impact strength, it is ideal for jobs were the ability to absorb abuse is a factor and in some cases may even need to save lives. A common material for high impact is Polycarbonate Sheet and Plate, but amazingly also Polycarbonate Rod.

Polycarbonate Sheets considered ‘unbreakable’.

Polycarbonate sheet is a valuable plastic due to its impact strength, temperature resistance and wide range of uses. It is commonly confused with Acrylic or Plexiglass which has similar properties but Polycarbonate is 25 times stronger and has a wider temperature range. Acrylic is better used for display purposes and is a brittle material. Polycarbonate is so strong that you can drill or hammer a nail right through it without breaking the material. It also can undergo large deformations without breaking while Acrylic cannot. Polycarbonate also can be used for electrical applications because it is a great insulator. It also has great safety properties due to it being flame retardant and because it has good heat resistance. Another way Polycarbonate exhibits its safety properties is through bullet resistant glass. Polycarbonate is the most commonly used material for bullet resistant glass, riot shields and face masks. In these situations, the Polycarbonate has a very high impact strength which is invaluable. It protects and saves lives and is able to stand up to abuse in dangerous situations.Polycarbonate Eye Protection Goggles

Polycarbonate Has Many Uses

From audio CDs to Blu-ray discs, airplane canopies to protective eye gear, Polycarbonate is a great thermoplastic (a material that can be formed and returned to its original shape) material for many different applications. Because of its impact strength and wide range of uses, Polycarbonate makes an ideal material for those who need peace of mind when designing or fabricating and need it to hold up to abuse and be virtually unbreakable. Polycarbonate is one of the toughest plastic materials around and everyday new products are being made from it. Whether using it for electrical, optical or for its impact properties, Polycarbonate is an ideal choice for many plastic needs.

Polycarbonate sheet (Makrolon) is available from .032″ – .500″ thick

Polycarbonate Plate, Slab, Block is available up to 4.0″ thick

Polycarbonate Rods are available from .250″ – over 8″ diameter.

More information on the UL approval ratings of Polycarbonate Sheets Here.

Not all Polycarbonate Sheet or Plate meet all approval ratings. Zelux Polycarbonate Plate is available in a machine grade and an optical grade. Zelux Polycarbonate Rod is also available – as a machine grade rod – not optical.

Which Plastic Sheet or Rod Material is right for me?

This not an easy question to answer. Several different factors come into play when choosing the right plastic for your application. Temperature, strength, exposure to the elements and even time spent at elevated temperatures are just a few factors to consider when choosing the right plastic for a particular project or job.Researching the best plastic sheet and rod materials

Picking the right plastic for your application is critical for its success and longevity and needed to insure that the material doesn’t fail in critical situations. From the onset it may take a bit of time to choose the right plastic material, but will ultimately pay off in the long run. Simply choosing the cheapest plastic sheet or rod may spell disaster for your project.

Many plastics are resistant to chemical attacks. Some plastics however are not. Two examples of plastic that have low resistance to chemicals are Acetal or Delrin (Dupont Brand Name) and Nylon. Acetal and Nylon are both a great machining plastics with excellent wear resistance and impact strength. However, when exposed to chlorine or alkaline they tend to become brittle which can cause failure and if used in such instances as plumbing, can lead to major problems such as flooding. Nylon does have good resistance to many chemicals but will degrade when exposed to acids especially sulfuric. A plastic that would work better for applications involving the use of chlorine or acids is UHMW. UHMW has some of the same properties as Acetal such as wear resistance, ease of machining and are both self lubricating. UHMW often is an alternative for Acetal and Nylon, especially when it comes to chemical attacks.Are you searching for the right plastic material for your project

Many plastic sheet and rod materials to choose from

Another plastic that can fail if used in the wrong application is Acrylic. Acrylic is a great plastic for displays and decorative purposes and is a natural replacement for window glass. However, it is brittle and has very low impact strength as opposed to Polycarbonate. Polycarbonate is a great plastic for impact strength, probably the best in the plastic family. It is 25 times stronger than Acrylic and this makes it ideal for bullet resistant glass and riot shields, while Acrylic would be useless for those critical jobs. However, Acrylic has better U.V. resistance than Polycarbonate Plastic Sheet which makes it better for use outdoors over longer periods of time because it is invisible to sunlight. Another plastic that cannot handle U.V. rays is Polypropylene. Polypropylene unlike Acetal has excellent chemical and moisture resistance. However, unlike Acrylic, it becomes brittle in sunlight and starts to craze or crack when exposed over a period of time while Acrylic would last many years longer. Even though Polypropylene is a very rigid and stiff material, with good impact and crack resistance, if exposed to the elements for a period of time, it will not retain its properties and a chemical chain reaction will cause the material to eventually fail. Polypropylene is great at handling chemicals and food applications which neither Acrylic nor Polycarbonate Sheet are well suited because for this application, because they don’t have good chemical resistance and the standard grades are not approved for handling food.

So many Plastic Sheet and Rod Choices

Because there are so many options, we invite you to do further research. One are would be the blog post ‘Pick The Proper Plastic Material‘, or even use the online tool ‘Gehr Plastic Selection Tool‘. There are over 60 standard plastic sheet materials that we stock, with many additional material that are available from our factories, contact us for help with your application.

These are just some examples of the differences between plastic resins and it is important to note that just because one plastic works for one application, it may not work for another. All factors must be considered and taken into account, maybe even some trial and error. This will insure that your project will go smoothly and will be able to last through many years of use, saving time, money and patience.
