(Teflon) Chinese trade names "TEFLON", "TEFLON", "TEFLON", "TEFLON", etc. It is a polymer compound polymerized from tetrafluoroethylene, which has excellent chemical stability and corrosion resistance (it is one of the best materials with corrosion resistance in the world today. Besides molten metal sodium and liquid fluorine, it is also resistant to all other chemicals, and can not change when boiling in "aqua regia". It is widely used in all kinds of chemicals that need to be resistant to acid, alkali and organic solvents), sealing and high lubrication Non sticky, electrical insulation and good aging resistance, excellent temperature resistance, working temperature: -180 to 260 C (can work at -60 to +250 C) for a long time.
Advantage:
It is commonly known as "king of plastics". Heat resistance, cold resistance, radiation resistance, chemical resistance, excellent weather resistance, excellent oxidation resistance in the atmosphere, excellent self-lubricating, excellent charge insulation.
Disadvantages:
Elasticity is slightly worse.
Application fields:
It is commonly used as the seal body of hydraulic and dust-proof seal, guide ring, support ring, retaining ring, etc., as well as the seal under high temperature and corrosion-resistant environment.
