Sabic Ultem® Resin Shortage Causing Delays

In September of 2014, Sabic announced issues with extended lead times for all Ultem® (PEI) Resins. These issues were caused by a dramatic increase in the demand this material. In addition, a scheduled outage at their Mt. Vernon facility is planned for April 2015.  Over the last several years, Sabic has increased capacity, and continue efforts to optimize production. Currently, Sabic is the only manufacturer of the PEI resin, under their trade name Ultem®.Ultem Sheet and Ultem Rod, PEI by Sabic, Polyetherimide

The result of an increase of industrial uses for Ultem® and spike in demand, along with the scheduled plant outage is a dramatic resin availability problem. Lead times from Sabic for Ultem® resin are currently being quoted at 14 – 18 weeks (as of Feb 2015).

The growth in the Sabic Ultem® plastic materials is due to many excellent physical properties that the Ultem has. The unique blend of UL 94 V-0 flame retardant properties, high heat resistance, superior resistance to autoclave sanitizing and is FDA/USDA and USP class VI compliant make Sabic Ultem® materials an obvious choice.

What this means if you use Ultem®

The available stock shapes of Ultem® 1000 and Ultem® 2300 our clients use is dwindling fast. We source sheet and rod  materials from all the major Sabic Ultem® stock shape manufacturers. Currently, many of our suppliers have zero inventory of resin or stock shapes. They are completely sold out, and as stated above, are not expecting any replacement resin for 4 or more months. Even then, the flow of resin will be reduced while production levels increase and catchup with current demand.

If Ultem® is what you must have, you have limited options. Industrial Plastic Supply, upon getting the news (see Press Release of Nov. 21, 2014) of the upcoming shortages, purchased all the Ultem® 1000 and Ultem® 2300 sheet and rod that suppliers had available. This large purchase was done to protect existing customers from a devastating outage, that could cause production slow downs or even shut downs. The common Ultem® shapes Sabic ultem shortage causing manufacturing delaysproduced are: Ultem® 1000 rod, Ultem® 1000 sheet, Ultem® 2300 rod, Ultem® 2300 sheet, and some Black Ultem® 1000 and Black Ultem® 2300 in sheet and rod. Contact Industrial Plastic to see if the Ultem® sheet or Ultem® rod material you need is still available.

What other options are available

In many cases, the Ultem® material that is specified may simply be unavailable for the foreseeable future. What options are available for other materials that may solve your immediate needs?

There are several materials that have many of the physical properties of the Sabic Ultem®. No one material has all the same properties as Ultem®, but several materials may work for your application. The determining factor will be the main physical properties you may need.

  • For High temperature resistance, look at: PTFE, PPS, PSU (Polysulfone), PPSU (Radel®) and PEEK
  • For Medical Applications, consider: PVDF (Kynar®), CTFE, PPSU (Radel®) and PEEK
  • For UL-94 V-0 requirements, investigate: PVC, PPS (Polyphenylsulfide), PTFE and PEEK

If you have specific properties or applications that you would like assistance with, please feel free to contact Industrial Plastic Supply, Inc. at 866-832-9315.

Trusscore PVC Wall Panels

Working on a demanding wall and ceiling project?

What types of things do you consider when you start a new construction project? You need to think about what materials you need. What materials will fit your application? For many commercial wall covering applications, the common wall covering is FRP (Fiberglass Reinforced Panels). While FRP is probably thought of first, there are a few draw backs for some applications.
The FRP panels are heavy, and normally require a two or more person installation team. Because it has fiberglass as a main component, it is messy and hard to cut. In addition, the FRP is not approved for food preparation areas. The new Trusscore PVC Wall panels are lightweight, easy to cut and fabricate, and can be easily installed on walls by one person.

Why Plastic Materials Get A Bad Reputation

On January 14, 2014, in Mentor Nuggets, by Plasticman

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…

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 me 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.

PVC Sheet and PVC Panels Go Way Beyond Pipe

When choosing a plastic raw material, the first step should be to look for the material with the proper physical properties. PVC (Polyvinylchloride or Rigid Vinyl) is an amazingly strong and versatile material that has proven itself a champion in the ever growing demand for mechanical grades of plastic. We can see its wide versatility in the way it is used and how it can keep up with the rough conditions it’s put under. PVC Pipe has been shown to take a beating in construction sites and it serves its purpose underneath our front lawns for our sprinkling systems. There are many more ways this strong industrial grade PVC can be used.

PVC Sheet and Rod for a wide variety of industrial and mechanical applicationsPVC sheet and PVC Rod can be machined easily

A standard industrial plastics, it is available as PVC Sheet or PVC Rod. The PVC, unlike other materials, is very easy to work with. It’s not necessary to buy expensive tools to get the job done. You can use the most of the same tools you would use on wood and steel. Unlike other materials, PVC can be kept cool easily using cold water or you can use an air compressor. Standard CNC equipment, punch machines, routers, drills and saws can all be used to shape PVC. If you wanted to seal and bond this material, that’s not a problem because like the PVC Pipe, the sheets and rods can be bonded with cements or heat welded. The cost of PVC is also lower than most other plastic materials that are harder to work with. So you can see why PVC should be on your short list of plastic materials.

Standard PVC sheet sizes and thicknesses for PVC Sheet

The standard sheet size for PVC is 48” x 96”. Some of you may know those measurements because that is also the standard size of drywall and plywood. Because PVC comes in the same sizes as other common materials it would be fairly easy to store. As for the thickness .062” – 3” are the most standard thicknesses, but it can be made thicker if needed. The material cuts and fabricates well, and we do offer cutting to your blank or precision sizes. We also cut the rest of the industrial and engineering plastics, including: Acetal/Delrin, Nylon, PEEK, Ultem, and dozens more; call for details.

PVC Sheets take a beating

PVC has many excellent properties, including the unbelievable UL 94 V-0 flame rating. This certification means that the Rigid Vinyl material is fire retardant, and is considered ‘self extinguishing. By now you are probably were thinking “PVC sounds great so far, but I wanted to paint and screen print on a material”, then have no fear because PVC Sheet and Sheeting is here! PVC is also known for its ability to hold paint and a screen print. It is heat bendable, vacuum formable in thinner gauges, and bondable to materials such as wood, paper and other plastics. Because of PVC’s many usages and qualities we even see it being use to create house hold items.

Various Thicknesses of Gray PVC Sheet and PVC Sheets, clear PVC sheet, type 1, type 2

The material can be sanded, routed and you can eliminate scratches and scrapes by simply buffing or sanding them away. With PVC being so versatile and also low in cost, it’s no wonder why it is a top choice for manufacturing and engineering companies. Click here for

More recycled plastic sheet is needed to fill demand

The plastic industry struggles with bad press over greater amounts of plastic in the land fills and oceans. This is understandable when the quantity of plastic products has skyrocketed. One of the biggest offender is the common shopping grocery sack. Most plastic materials are recyclable, and the demand has grown much faster than the supply.

Recycled resin demand drives support for EPR

By Mike Verespej| PLASTICS NEWS STAFF

Listing of recycled plastic sheet materials

Posted May 22, 2012

WASHINGTON (May 22, 10:35 a.m. ET) — With demand for recycled resins continuing to outstrip supply, the voices are getting louder — and more organized — for creating some sort of extended producer responsibility program to increase the recycling of packaging materials, plastics and otherwise.

In the past two months, an alliance of more than 30 public interest groups and other supporting organizations formed the Cradle² coalition to push for public policy changes that would make manufacturers responsible for collecting and recycling the products and packaging they make.

“The broad implementation of EPR is still a long way off,” said Scott Mouw, recycling director for the state of North Carolina. “But these new advocacy groups for EPR are all reacting to the same thing. …(read more here)

The entire plastic supply chain has been affected. We receive calls regularly for our plastic materials, but clients want to know if they can get a recycled plastic sheet version. Most plastics we carry can be recycled, but most don’t make it back into sheets or rods due to FDA and NSF requirements. The most popular plastic we carry that are available as a recycled product are Reprocessed UHMW Sheets and Rods and Repro HDPE. The HDPE is available as post consumer content from milk jugs and laundry soap containers. PTFE sheet is also available as a reprocessed product for applications where the high purity is not critical, just the heat or wear resistance would remain.

Not All Plastic Suppliers Are Created Equal

Big Differences Between Plastic Suppliers

While you can purchase a piece of plastic from many different suppliers, there are some significant differences between these suppliers. Some of the main differences are in the manufacturers and the materials that you get supplied. plastic sheet suppliers, plastic suppliers, Greatly stressed plastic sheet - nylon with large warp

We see a wide range of materials and some drastically inferior grades of materials being sold to clients. Some materials have been produced too quickly or cooled too quickly causing a very high stressed plastic piece. These high stressed materials will warp, twist or crack when they get heated or during cutting. This material on the right is a piece of highly stressed Nylon. While cutting the material, our new customer had to stop the saw due to the severe warping and binding of the saw by this material. This new client brought this 24″ long part, and asked if we would cut it for him. We bought this part from him as an excellent example of a high stress plastic. (We did cut a quality piece of material to solve his problem). Other things you should consider when choosing a quality plastic supplier:

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 – 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 known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.
