Polytetrafluoroethylene emulsion (PTFE)

Polytetrafluoroethylene (also known as PTFE, Teflon, Teflon) has outstanding excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, and a very low friction coefficient. Used as engineering plastics, it can be made into polytetrafluoroethylene pipes, rods, strips, plates, films, etc., and is generally used in corrosion-resistant pipelines, containers, pumps, valves with high performance requirements, as well as radars, high-frequency communication equipment, radio equipment, etc. By adding any filler that can withstand the sintering temperature of PTFE to PTFE, the mechanical properties can be greatly improved while maintaining other excellent properties of PTFE. The filled varieties include glass fiber, metals, metallized oxides, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL, etc., and the wear resistance and limit PV value can be increased by 1000 times.

PTFE is one of the best corrosion resistant materials in the world and is known as the "King of Plastics." Polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE, and its trade name is "Teflon" or "Teflon". The basic structure of polytetrafluoroethylene is: -CF2-. Polytetrafluoroethylene is widely used in various places that require acid, alkali and organic solvents. It is not toxic to humans itself, but ammonium perfluorooctanoate (PFOA), one of the raw materials used in the production process, is considered to have carcinogenic effects. Can work for a long time at temperatures from +250℃ to-180℃, and can withstand all other chemicals except molten metal sodium and liquid fluorine.
