FEP（Fluorinated ethylene propylene),It is a copolymer of tetrafluoroethylene and hexafluoropropylene. FEP can be applied to soft plastics, and its tensile strength, wear resistance, creep resistance are lower than many engineering plastics, and it has a low dielectric constant over a wide temperature and frequency range.
The material does not ignite, it have excellent wear resistance and low coefficient of friction. It can be made into granular products for extrusion and molding and used as powders for fluid beds and electrostatic finishing, Also can made into aqueous dispersions . Semi-finished products include films, plates, rods, electrodes, special-shaped parts and single fibers. Mainly use is to make the inner lining of pipes and chemical equipment, the surface layer of rollers and various wires and cables.
