Pure PTFE Gasket is made by cutting and moldeding, into flat shape, V shape gasket and valve annulus. It has 100% PTFE structure. It can be bear the most bitter chemical medium, and has good anti-creeping performance 
 

• Lowest coefficient of friction of any known material.
• PTFE operates up to 500° F.
• Tremendous chemical resistance
• PTFE is an excellent insulator of heat and electrical charges
• Limitations: PTFE has low compressive & tensile strength.

Size: Customized

PTFE is a fluoropolymer 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.
