After processing, PTFE has excellent chemical stability and corrosion resistance. Polytetrafluoroethylene is also one of the best materials in the world. Corrosion resistance. In addition to the molten alkali metal and chlorine trifluoride, it is resistant to all other chemicals, even when boiled in aqua regia. PTFE is widely used in various occasions where acid, alkali and organic solvents are needed. It has sealing, high lubricity and non viscosity, good electrical insulation, excellent aging resistance and excellent heat resistance. Polytetrafluoroethylene itself is a non-toxic material for human beings.

The service temperature of PTFE is - 190-250 ℃, which can be rapidly cooled and heated, or alternatively heated and cooled. Pressure - 0.1-6.4mpa (full vacuum to 64kgf / cm2) (full vacuum to 64kgf / cm2) various profiles and parts made of PTFE rod, tube, film, bearing, gasket, valve, etc. are widely used in mechanical, chemical industry, aviation, electrical and electronic, national defense industry, cutting-edge technology, medical and health, electrical insulation and other fields.

The production of polytetrafluoroethylene solves many problems in chemistry, petroleum, pharmaceutical and other fields. PTFE Seal, Gasket and Gasket are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, polytetrafluoroethylene (PTFE) has chemical resistance, which has been widely used as sealing and filling materials. The dispersion can be used as insulation impregnation solution of various materials, as well as anti-corrosion coating of metal, glass and ceramic surfaces. All kinds of PTFE rings, PTFE gaskets, PTFE fillers are widely used to seal all kinds of anticorrosive pipe flanges. In addition, it can also be used for the drawing of polytetrafluoroethylene fiber - fluorine fiber (foreign trade name is PTFE).
