Product Description:

PTFE has the highest melting point and is capable of continued service at -180-260 C. PTFE is a melt processible resin capable of continued service at 204 C. PTFE products are used as gasket and packing materials in chemical processing equipment; as electrical insulation for maximum reliabillity; and in bearings, seals, piston rings and other mechanical applications, especially those require anti-stick characteristics. PTFE has excellent thermal and electrical insulation properties. it has a low coefficient of friction.
