What is the difference between PTFE, FEP, PFA, and ETFE?

Teflon PTFE: Teflon PTFE: Teflon PTFE: Teflon PTFE: Teflon PTFE: Teflon PTFE: Tefl The non-stick coating PTFE (polytetrafluoroethylene) may be used continuously at 260°C, with a maximum operating temperature of 290-300°C, and has a very low friction coefficient, excellent wear resistance, and chemical stability.

Teflon FEP: A non-stick coating made of FEP (fluorinated ethylene propylene copolymer) that melts and flows during baking to form a non-porous film with great chemical stability, outstanding non-stick qualities, and a maximum service temperature of 200 degrees Celsius.

PFA (perfluoroalkylate) non-stick coatings melt and flow when baked to generate a non-porous film similar to FEP. PFA has the advantages of a higher continuous usage temperature of 260° C, greater rigidity and toughness, and is particularly well suited to anti-sticking and chemical resistance under high temperature settings.

ETFE (ethylene-tetrafluoroethylene copolymer): ETFE is an ethylene-tetrafluoroethylene copolymer. This resin is the toughest fluoropolymer, capable of forming a long-lasting coating with exceptional chemical resistance and continuous use at 150°C.
