Polytetrafluoroethylene can be formed by compression or extrusion processing; it can also be made into water dispersion for coating, impregnation or fiber. Polytetrafluoroethylene is widely used in industries such as nuclear energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, metal surface treatment, pharmaceuticals, medical treatment, textiles, food, metallurgy and smelting, etc. , Corrosion-resistant materials, insulating materials, anti-stick coatings, etc., making it an irreplaceable product.
PTFE has outstanding excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, and very low friction coefficient. Used as engineering plastics, it can be made into polytetrafluoroethylene pipes, rods, strips, plates, films, etc. It is generally used in corrosion-resistant pipelines, containers, pumps, valves, radar, high-frequency communication equipment, etc. with high performance requirements. Radio equipment, etc. Adding any filler that can withstand the sintering temperature of PTFE can greatly improve the mechanical properties while maintaining other excellent properties of PTFE. Filled varieties include glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL... etc. The wear resistance and limit PV value can be increased by 1000 times.
The polytetrafluoroethylene pipe is made of suspension polymerized polytetrafluoroethylene resin through plunger extrusion processing. Among the known plastics, polytetrafluoroethylene has the best chemical resistance and dielectric properties. Polytetrafluoroethylene braided packing is a good dynamic sealing material. It is woven from expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing, no hydrolysis, no Excellent performance such as hardening. Used for gasket seals and lubricating materials that work in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used under various frequencies.
