This type of gaskets are made of expanded PTFE gasket material, designed for use in process piping and equipment in chemical, pulp and paper, food and beverage, and other general industrial applications where resistance to highly aggressive chemicals is required. The EPTFE gasket can handle temperature of about 240°C.
Expanded PTFE gaskets are ideal for use in steel flanges and flanges with irregular surfaces. The expanded PTFE gaskets conform to the FDA requirements.
The expanded PTFE gaskets has the same chemical resistance as the normal PTFE gaskets, but has better flexibility and elasticity. The expanded PTFE gaskets we cut is made only from pure PTFE resins. It is suitable for use in steel flanges as well as flanges where a highly compressible gasket is required. EPTFE gasket is also suitable for sealing flanges with irregular surfaces.
Expanded PTFE sheet material and the gaskets made of it will not exhibit the cold flow problems associated with virgin PTFE or the hardness problems of some other filled PTFE products. The gaskets from expanded PTFE have excellent sealability, cuts easily, and separate cleanly from flanges after use.
