PTFE Sheet and Film

PTFE is a fluorocarbon-based polymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. PTFE's low coefficient of friction makes it suitable for applications where sliding action of parts is needed: such as plain bearings, gears, and slide plates. In these applications, it performs significantly better than nylon and acetal; and is comparable to UHMW. PTFE however can be used over a far wider temperature range than these materials; -100°F to +400°F (-73°C to 204°C) and offers superior electrical insulation properties. Although its' mechanical properties are low compared to other engineering plastics, those properties can be enhanced through the use of additives such as Carbon, Graphite, Bronze, and Glass Fiber.

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 reliabillity; 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. It is difficult to make anything adhere to PTFE. A material may stick to it, but the material can be peeled off or rubbed off.
