Moulded PTFE Bar

The PTFE molded bar is a bar made of a suspension resin which is formed by a molding method and then sintered at a high temperature. It is mainly used for some long products and non-standard mechanical parts: seals/gaskets, rings, wear plates/seats, insulation parts, corrosion resistance industry, mechanical parts, linings, oil and gas, petrochemical Industry, chemical industry, equipment and so on....

PTFE bars are available in push bars and molded bars. In known plastics, PTFE has the best chemical and dielectric properties and can be used at temperatures from -180 ° C to +260 ° C. And with the lowest coefficient of friction, mainly for some long products and non-standard mechanical parts: seals / gaskets, rings, wear plates / seats, insulation parts, corrosion resistance industry, mechanical parts, lining, Oil and gas, petrochemical industry, chemical industry, equipment manufacturers, etc.

Product Features

Main features of PTFE rod:

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.
