(PTFE) products are made of polytetrafluoroethylene (PTFE) resin, sintered after cold pressing in a mold, with excellent corrosion resistance, good self-lubrication and non-adhesion. Therefore, the products are resistant to almost all chemical media, and have wear resistance, pressure resistance, low friction coefficient. It is widely used in petroleum, chemical, metallurgical machinery, transportation, medicine, food, electric power and many other fields. PTFE moulded tube is made of suspension polymerization PTFE resin by moulded processing. Polytetrafluoroethylene in plastics has the best chemical corrosion resistance and dielectric properties, can be used in the temperature range of -180℃- +260℃. [Usage] Used for the manufacture of advanced insulation, anti-corrosion, anti-stick parts and conveying a variety of strong corrosive fluid pipe, corrosion medium container, pipe gasket sealing wire seal.
