Polytetrafluoroethylene (English abbreviation for Teflon or PTFE, F4), because of its wide application, is known as the "King of plastics", Chinese transliteration known as "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon" and so on. Polytetrafluoroethylene is made of tetrafluoroethylene polymerization of polymer compounds, with excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today, in addition to molten metal sodium and liquid fluorine, the ability of all other chemicals, boiling in aqua aqua can not change, Widely used in various conditions requiring acid, alkali and organic solvent resistance), sealing, high lubrication, non-viscosity, electrical insulation and good anti-aging, temperature span (can work in +250℃ to -180℃ temperature for a long time). Teflon itself is not toxic to humans, but perfluorooctanoic acid (PFOA), one of the raw materials used in the manufacturing process, is thought to be possibly carcinogenic.
Its birth has solved many problems in chemical, petroleum, pharmaceutical and other fields. It has been widely used as sealing material and filling material.
High temperature resistance -- operating temperature up to 260℃.
