MAIN FEATURES OF PTFE
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.
APPLICATION
has excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubrication, excellent dielectric properties and very low friction coefficient. Used as engineering plastics, it can be made into polytetrafluoroethylene pipes, rods, belts, plates, films, etc. It is generally applied to corrosion-resistant pipes, containers, pumps, valves, radar, high-frequency communication equipment, radio equipment, etc. with high performance requirements. The mechanical properties of PTFE can be greatly improved by adding any filler that can withstand the sintering temperature of PTFE while maintaining other excellent properties of PTFE. The filled varieties include glass fiber, metal, metalized oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL…, etc. the wear resistance and limit PV value can be increased 1000 times.
Polytetrafluoroethylene pipes are made of suspension polymerized polytetrafluoroethylene resin through plunger extrusion processing. Among the known plastics, polytetrafluoroethylene has the best chemical corrosion resistance and dielectric properties. braided packing is a kind of good dynamic sealing material, which is woven from expanded poly (vinyl chloride) strips and has excellent properties such as low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis, no hardening, etc. Gasket seals and lubricating materials used in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used at various frequencies.
