PTEF rubber joint's  raw materials is ptfe board,It is composed of tetrafluoroethylene by polymerization of polymer compounds.Short form for its structure - / - CF2 - CF2 - n -, It has excellent chemical stability, corrosion resistance.teflon is called PTEF or F4 for short.It is one of the most corrosion resistant material is the world.

It is one of the best  corrosion resistance plastic.It is not affected by known corrosion of acid, alkali, salt, antioxidant. Even the Aqua regia helpless for it. So called  plastic king.

Added into the molten metal sodium and Liquid fluorine,can resistance all other chemicals.Widely used in various need resistance to acid and alkali and organic solvent.It can working for a long time at the temperature of + 250 ℃ to -180 ℃ .

PTEF rubber joint when used in special environment. Add a layer of teflon plate in its inner wall can have high temperature resistance,acid and alkali resistance, wear-resisting and so on.
