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 GP
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.
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. Covestro/Sheffield manufacturers this premium quality polycarbonate sheet right here in the good old USA, in Sheffield, Massachusetts. They produce this crystal clear sheet on the latest and most technologically advanced extruders available, and have several warehouses for us to get material quickly for you. Why settle for an unknown? Can you afford to ‘try’ the other guys? Step up to the finest quality, and yet still competitively priced polycarbonate sheet, get Covestro Makrolon GP Polycarbonate Sheet for your next project. Industrial Plastic Supply also carries the Westlake Zelux M Polycarbonate Sheet and Zelux W Polycarbonate Plate. The Zelux M is a machine grade Polycarbonate Plate from .375″ – 4″ thick sheet, and the Zelux W is a clear – Window Grade thick Polycarbonate Plate in the same thickness range. Contact us for more information on this thicker material. We also supply other manufacturers grades of Polycarbonate Plate, including, but not limited to: Ensinger Plastics, Nytef Plastics, Rochling Plastics and more. Contact us for more information or technical assistance on Polycarbonate or any other quality plastic sheet, rod or tube. Call us at 866-832-9315 or send us a quick note here. Google+
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 referred 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 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.
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.
Typical Polycarbonate Resin Properties:
|Tensile Strength Yield
||8,900 – 9,000
|Izod Impact – Notched
|Hardness – Rockwell
