PTFE (DuPont trade name Teflon). It is a macromolecule compound polymerized from tetrafluoroethylene. Its simple structure is -[-CF2-CF2-]n-. It has excellent chemical stability and corrosion resistance. It is the most corrosion resistant in the world today. One of the best materials, in addition to molten alkali metal, chlorine trifluoride, chlorine pentafluoride, and liquid fluorine, can withstand all other chemicals, boil in the aqua regia also does not change, is widely used in various needs of anti-acid and organic Solvent occasions. Sealed, high lubricity, non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can work in the long-term temperature of 280 °C to -180 °C). PTFE itself is not toxic to humans. Use temperature -190 ~ 250 °C, allow quenching and heat, or hot and cold alternate operation. Pressure -0.1 ~ 6.4Mpa (Full vacuum to 64kgf/cm2), Its production has solved many problems in the chemical, petroleum, pharmaceutical and other fields.
