Product Features

Main features of PTFE gasket :

1. Temperature resistance ---It is able to work stably between -180°C to +260°C.

2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.

3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.

4. Anti-aging, weathering resistance.

5. Excellent insulation property.

6. Filled material: Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.
