After processing, teflon Excellent chemical stability and corrosion resistance. Polytetrafluoroethylene is also one of the best materials in the world today. Corrosion resistance. In addition to the molten alkali metal and chlorine trifluoride, it can also withstand all other chemicals and will not change even when boiling in aqua regia. teflon In modern times, it is widely used in various occasions where acid resistance, alkali resistance and organic solvents are required. It has sealing property, high lubricity and non stickiness, good electrical insulation, excellent aging resistance and excellent heat resistance.

Polytetrafluoroethylene The operating temperature is - 190~250 ℃, which can be rapidly cooled and heated, or alternatively heated and cooled. Pressure - 0.1~6.4 Mpa (full vacuum to 64 kgf/cm2) (full vacuum to 64 kgf/cm2) It is made of PTFE rod, tube, membrane, bearing, gasket, valve, etc.

The production of PTFE has solved many problems in chemistry, petroleum, pharmacy and other fields. teflon The seals, gaskets and gaskets are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, teflon With chemical resistance, it has been widely used as sealing material and filling material. Dispersions can be used as insulation impregnation solutions for various materials, as well as anti-corrosion coatings on metal, glass and ceramic surfaces. Various PTFE rings, PTFE gaskets, PTFE fillers, etc. are widely used to seal flanges of various anti-corrosion pipes. In addition, it can also be used for polytetrafluoroethylene fiber - fluorine fiber (foreign trade name: Teflon ）Stretch of.
