FEP
Non Melt
Melt
FEP (fluorinated ethylene propylene) is chemically a copolymer of hexafluoropropylene and tetrafluoroethylene with good thermal stability, outstanding chemical inertness, good electrical insulation and low friction coefficient. It possess most of the excellent physical, chemical and electrical properties of PTFE fluoropolymer resin with the ability to be processed using melt processing equipment’s. It differs from the PTFE (polytetrafluoroethylene) resins in that it has a lower melt viscosity than PTFE and can be processed like other thermoplastic resins and is melt-processible using conventional injection molding and screw extrusion techniques. It is normally inert to liquid oxygen and is weathering resistant.
Working Temperature Range: -29deg. C to 150deg. C
Classification:
- Extrusion grades
- Molding grades
- Dispersion grades
- Coating grades
