The main varieties are polytetrafluoroethylene, tetrafluoroethylene-ethylene * * * polymer, tetrafluoroethylene-hexafluoropropylene * * * polymer and chlorotrifluoroethylene-ethylene * * * polymer. Because the molecular structure of fluoroplastics contains fluorine atoms, it has many excellent properties, such as excellent electrical insulation, high heat resistance, outstanding oil resistance, solvent resistance and wear resistance, good moisture resistance and low temperature resistance.
Therefore, fluoroplastics play an important role in national defense, electromechanical, metallurgy, petrochemical and other industrial sectors.
