Fluorinated ethylene propylene copolymer
FEP, or Teflon-FEP®, is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE (polytetrafluoroethylene) resins in that it is melt-processible using conventional injection molding and screw extrusion techniques.
Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon-FEP®. Similar products are available from Dyneon and Daikin with the brand name of Neoflon-FEP®.
FEP shares PTFE's useful properties of low friction and non-reactivity, but is more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to UV radiation.
