It retains most of the desirable characteristics of polytetrafluoroethylene (PTFE) but with a melt viscosity low enough for conventional melt processing. Perfluorinated ethylene-propylene (FEP) is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). Like PTFE and FEP, it is fully fluorinated. 4, 0. In this work, a protective FEP coating was deposited on a stainless-steel substrate using the air spray process and then cured to obtain a compact and uniform film. FEP is a thermoplastic copolymer, which is characterized by a lowered tensile strength and a very clogged surface. alysts the final product Cyclic Olefin Copolymer is generated. It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. Since 1988 FEP is the abbreviate form for coplymers consisting of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). (1), the film-transducer sensitivity is associated with the piezoelectric d 33 coefficient of piezoelectret film. The global fluoropolymers market size was USD 6.
