High-Density Polyethylene (HDPE) sheet is extremely strong against impact, abrasion-resistant, and exhibits a low coefficient of friction. The material is also moisture, stain, and odor-resistant, and is FDA approved for use in the food processing industry (mainly for cutting boards). The material’s durability makes it a perfect match for a variety of applications such as water tanks, chute linings, bottle/bottle cap production, and numerous other industrial uses. Borated HDPE offers radiation protection in nuclear facility applications.

PTFE has the highest melting point and is capable of continued service at 500F(260 C). FEP is a melt-processible resin capable of continued service at 400F(204 C). PTFE products are used as gasket and packing materials in chemical processing equipment; as electrical insulation for maximum reliability; and in bearings, seals, piston rings, and other mechanical applications, especially those requiring anti-stick characteristics. PTFE has excellent thermal and electrical insulation properties. And, it has a low coefficient of friction.
