Application range of ptfe coating

Ptfe coating is also called polytetrafluoroethylene, which can be formed by shrinking or extrusion processing; it can also be made into water dispersion for coating, impregnation or fiber. Polytetrafluoroethylene is widely used in nuclear energy, defense, aerospace, electronics, electrical, chemical, machinery, instrument, meter, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgical and smelting industries. , Anti-corrosion materials, insulation materials, anti-stick coatings, etc., making it an irreplaceable product.

PTFE has excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-smooth dielectric properties, and low coefficient of friction. Used as engineering plastics, can be made of PTFE pipes, rods, tapes, plates, films, etc., generally used in corrosion-resistant pipes, containers, pumps, valves and radar, high-frequency communication equipment, Radio equipment, etc. By participating in any filler that can accept the sintering temperature of PTFE, the mechanical properties can be greatly improved, while maintaining other properties of PTFE. Filling types include glass fiber, metal, metalized oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL, etc., and the wear resistance and limit PV value can be increased by 1000 times.

The PTFE pipe is made of suspension polymerized PTFE resin and processed by plunger extrusion. Polytetrafluoroethylene has better chemical resistance and dielectric properties in known plastics. Teflon braided packing is a kind of good dynamic sealing material. It is woven from expanded polytetrachloroethylene tape. It has a low coefficient of friction, abrasion resistance, chemical resistance, good sealing, no hydrolysis, no Hardening and other properties. Used for gasket seals and smooth materials working in various media, as well as electrical insulators, capacitor dielectrics, wire insulation, electrical instrumentation insulation, etc. used at various frequencies.
