ETFE (Ethylene-Tetrafluoroethylene) delivers the greatest strength and abrasion resistance of the TFE copolymers and has a continuous service range temperature range of 150°C

PFA (Perfluoroalkoxyethylene-Tetrafluoroethylene) is the most similar to PTFE in terms of chemical and physical behavior. PFA also has the added benefit of a higher service temperature (260°C) over FEP.

FEP (Fluorinated Ethylene Propylene) is similar in chemical and physical behavior to PFA, but provides a lower service temperature at 200°C and is slightly less susceptible to water absorption than most other fluoropolymers.
