Polytetrafluoroethylene has good chemical corrosion resistance and dielectric properties in known plastics. Polytetrafluoroethylene braided packing is a kind of good dynamic sealing material, which is woven by expanded polytetrafluoroethylene tape. It has the advantages of low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, non hydrolysis, unchanging hardness, etc. Gasket seals and lubricating materials used in various media, as well as electrical insulation parts, capacitor media, wire insulation, electrical instrument insulation, etc. used in various frequencies. Polytetrafluoroethylene film is suitable for insulation layer, conductor insulation, electrical instrument insulation and sealing gasket of capacitor medium and special cable, as well as non stick tape, sealing tape and demoulding.
In order to improve the creep property and wear-resistant function of polytetrafluoroethylene, graphite, carbon black, molybdenum disulfide, glass fiber, carbon fiber, polyphenylene sulfide and other main materials were used to fill and modify polytetrafluoroethylene. Main uses: gasket, valve seat, seal, bearing, slider, piston ring, etc.
Teflon Filled Products are made of high-strength fiberglass yarn, which are woven into various thickness of base cloth, then impregnated with Teflon and treated with high-temperature silica gel. Main uses: textile printing and dyeing, printing drying guide belt, screen printing, UV drying, food baking machine guide belt, food, medicine, composite plastic bag heat sealing, anticorrosive pipe lining, etc.
Polytetrafluoroethylene (PTFE) filling products are widely used. PTFE materials have many characteristics such as excellent resistance, weatherability and low permeability. It can prevent metal corrosion in the transportation and manufacturing process of chemical plants, such as chemical plants and waste incineration plants, extend the service life of equipment, and reduce the frequency of accidents. In addition, with the increasingly strict requirements of automobile emission standards and environment, the performance requirements of automobile parts are higher and higher, and the heat-resistant, oil resistant and low permeability of polytetrafluoroethylene material make it more and more widely used in the field of automobile.
