The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP, is a class of chemical substances.
FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene.
FEP crystal melting point is 304℃, density is 2.15g/CC (grams/cubic centimeter).
FEP can be applied to soft plastics, and its tensile strength, abrasion resistance, and creep resistance are lower than many engineering plastics.
It is chemically inert and has a low dielectric constant over a wide range of temperature and frequency (2.1)
