PCTFE has a low melt viscosity which permits extrusion, compression moulding and injection moulding. Typical uses include valve seats, seals, sight glasses and windows and many cryogenic applications.
Valve SeatsPCTFE's stability at low temperature makes it an ideal choice as a ball valve seat or butterfly valve seat material.
SealsPCTFE is a great material for specific sealing applications and our team of experts can help you choose the best performing seal solution for your operating conditions.
application:
1. Contact with highly corrosive media, sealing and gasket materials of high-pressure systems, transparent materials for observation windows, etc.
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE is used as sealing fluid, grease for highly corrosive media and balancing fluid for navigation gyros.
PCTFE rod offers outstanding chemical resistance and cold flow resistance, making it ideal for demanding applications.
