s PTFE and FEP (fluorinated ethylene-propylene)
Fluorinated ethylene propylene

Fluorinated ethylene propylene, Teflon-FEP, 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....
. PFA and FEP both share PTFE's useful properties of low coefficient of 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.

Another version of polytetrafluoroethylene perfluoro methylvinylether, with a different ratio of PTFE and MVE monomers from PFA, is MFA.
