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.

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.

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.

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.

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 Shields Is Makrolon Polycarbonate The Strongest Plastic in Sheets? Is Makrolon Polycarbonate The Strongest Plastic in Sheets? polycarbonate sheet 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 Is Makrolon Polycarbonate The Strongest Plastic in Sheets?

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.

Plastics In Natural Disasters

The world is an ever changing and frequently hostile environment. Damage can be caused by a range of factors: from storms, floods and tornados to fires, hurricanes and earthquakes – all natural disasters.

This is certainly evident in the recent earthquakes and tsunami that ravaged Japan and Haiti. In addition, we have man made disasters. The nuclear concerns in Japan have captivated people’s attention throughout the globe. The Gulf Oil Spill is an example of another environmental disaster. Plastic materials are the perfect choice in prevention, preparedness and clean up from natural disasters.

 

Plastics in disaster preparedness.

Many plastic materials are used in the prevention, control and repair management – whenever and wherever a natural disaster may occur.

Polycarbonate Window Screen - Protecting against Natural Disasters Plastic Materials In Natural Disasters Plastic Materials In Natural Disasters Polycarbonate2

One of the most visible plastics is the Polycarbonate used in hurricane window covers / shutters. Polycarbonate is a clear rigid plastic that has extremely high impact strength, and is the material most commonly known as ‘Bullet Resistant Glazing’. It is used in safety glasses, riot shields and bank theft prevention glazing. The Polycarbonate protects windows and inhabitants from flying debris and breaking glass caused by the high winds, hurricanes and tornados. Use of the Polycarbonate window coverings saves homes from damage, and helps reduce insurance premiums.

Hillsides are affected by storms and heavy rains, causing mud slides. The standard and most popular solution is to cover hillsides with Polyethylene film. This helps to prevent the rains from saturating the ground and causing the ground to move or shift. The Poly film is normally .004” – .010” thick in widths up to 20 feet and lengths of 100 feet (the same material used as painters tarps from home improvement centers). This film is then attached to the hill with spikes, stakes or sand bags; and this material sheds the water rather than letting it soak in. It can be applied with folds and used like rain gutters to direct water flow away from specific areas. Also, the current sand bags used are not the old cotton fabric bags used years ago; they are now a high strength and tear resistant woven polypropylene ‘fabric’ bag.

 

The recent critical issues with nuclear leaks bring up an interesting use of a plastic material. As you may recall, after the earthquake and tsunami, the Japanese energy experts were pumping water and boron into the reactors to help control the amount of nuclear energy released. Boron Filled Polyethylene Helps Protect Against Radiation Disasters Plastic Materials In Natural Disasters Plastic Materials In Natural Disasters PolymerBoronSheild22The nuclear industry uses a plastic material, High Density Polyethylene (HDPE) that has been filled with the natural mineral boron. This boron filled (typically a 5% boron fill) is used to shield neutrons and nuclear energy in many applications; nuclear submarines, nuclear power plants, hospital radiation, dental x-ray shielding and industrial radiation applications. It is normally produced in sheet, and can then be mounted in and around the radiation source as shielding. The benefit to using this boron filled HDPE is this sheet weighs significantly less than traditional lead shielding, and is therefore much easier to install.

 

Plastic used in clean up from disasters

It is much more difficult to clean up after natural disasters occur. Many of the methods used in the preparation limit the amount of clean up caused by natural disasters.

Depending on the severity of the natural disaster, the uses of plastics in the aftermath are almost limitless. In the cleanup and rebuild after major Earthquakes, shelter is a key component. One of the quick shelters brought in are simple wooden frames with twin-wall plastic sheets made from either Polypropylene or Polycarbonate stapled or nailed to the framework. This provides an inexpensive, easily movable and effective shelter for short term housing. The twin-wall design provides excellent insulation and energy savings. This style shelter is foldable, easy to transport and very easy to set up. Several versions can be made from small huts to larger family areas, to separate sanitary latrine units. These extruded twin-wall materials work well to protect against rain and excessive exposure to the elements. These can be used as assembled, or with a sand bag reinforced perimeter. In Haiti, there were reports of residents filling used one gallon water bottles with mud, and building shelters with these mud building blocks.

The gulf oil spill brought plastics to the front line in disaster cleanup again. Materials used to collect and dispose of excess oil from the waters were rushed to the area. Polyethylene bags are used to collect the oil covered and saturated cleaning rags and clothes, preventing additional dispersion. Many varieties of machinery were brought in to clean the waters. One style machine uses 8” UHMW rod as a squeegee roller that grabs the oil from the water surface and then collects it for later use. Oil booms and rotary wheels are common systems for collecting oil from spills. Because plastics have great surface tension, the oil ‘sticks’ to the plastic surface during the cleaning process. Then the plastic surfaces are wiped clean for reuse and capturing the oil. Plastic tubes and hoses are used to move the oil after collection.

A significant use of plastics would be in the aftermath of natural disasters, specifically in the sanitation and clean water areas. First is sanitation; plastics are used in keeping items clean and dry. Polyethylene film covers items such as medical supplies, shelters, clothing and food cartons. This film keeps the items protected during shipment and ready for use.

Water is the second area of concern. Clean water is critical during the clean up and resettling after a natural disaster. Individual use water bottles are the quick and easy way to deliver water. Larger rotationally molded tanks are brought in with the ability to store large amounts of water in the areas affected. Reverse osmosis equipment (many components are made from plastic) is brought in to convert contaminated water in the clean potable water on site.

In all of these examples, plastic is lighter in weight than the alternatives, normally less expensive that the alternatives, it lasts longer and the plastics are recyclable.

Plastics are excellent choices for material to use in natural disasters.

Plastic Materials That Are UV Stable

Some of our most popular questions include “Is this material UV stable”, or “How long will this last in direct sunlight”, or something similar.

These are great questions. Just look at the ‘cheap’ backyard furniture you bought last year at the big box store, yep, it is faded and cracking. Why is that?

The quick answer is the material had either no UV (Ultra Violet Light) stabilizer or very, very little. Most plastic materials are not UV stable to start with, the main exception is Acrylic Sheeting which is virtually invisible to UV.

All other plastic materials need a little something extra to give it the protection it may need from the sun. Many plastic materials, if given the proper additives, can be used in direct sunlight for 10 – 15 years (or longer) giving excellent performance. UV Stable Playground HDPE Sheet Which Plastic Materials Are UV Stable - Stablized Which Plastic Materials Are UV Stable - Stablized play

The first factor in picking such a material is the intended use. Not all materials are good candidates for all applications.

While some materials will perform very well, others under the same conditions will fail. Please contact us for details on a material to meet your needs.
HDPE sheet is one of the best materials for long term outdoor use, if given the proper additives. Next time you drive by a children’s playground in your local city, look at the brightly colored panels used to make the play equipment. This is a HDPE sheet with some heavy UV additives, and this makes an excellent application. These UV stabilized HDPE sheets are available in a rainbow of colors and are able to be easily fabricated, this material is excellent for many outdoor applications.
If your application is more mechanical and will not be exposed to direct sunlight, other materials that you might use would be: Polycarbonate, UHMW, ABS (especially with Korad cover), Acetal, Noryl and many more.

Our standard Covestro Makrolon Polycarbonate is a UV stable material in sheet, and is frequently used in replacement glazing applications. The remaining materials on the list are available in Black (a carbon black pigment) which extends outdoor usage. While still not recommended for direct sunlight, they can be used with a good possibility of success – depending on design.

Plastic materials have a tendency to become brittle or lose properties over time with sun exposure, if material does not have enough or proper UV stabilization. When using the proper material that contains the proper additives or coating, you can expect years of trouble free service.


Additionally, many materials will work well if they are painted to cover the plastic surface. Many spray paints, especially Acrylic paints, last many years in the sun. Please check with us, as some material do not accept paints or coatings.


Take some time to review your requirements, and the properties of the plastic you intend to use. The right material will provide the best performance. Contact any of our Plasticologists for assistance, call 866-832-9315 or email us. You can always do research on materials at www.iplasticsupply.com
