FEP

Fluorinated ethylene propylene or FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE resins in that it is melt-processible using conventional injection molding and screw extrusion techniques. FEP was invented by DuPont and is sold under the brandname Teflon® FEP. Other brandnames are Neoflon® from Daikin or Dyneon® FEP from Dyneon/3M.

FEP is very similar in composition to the fluoropolymers PTFE and PFA. FEP and PFA both share PTFE's useful properties of low friction and non-reactivity, but are more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to sunlight.
