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.
