What are the primary differences between PTFE, FEP, and PFA fluoropolymer cables?

While all three are high-performance fluoropolymers, they serve different manufacturing and installation needs:

PTFE (Polytetrafluoroethylene): Rated up to 260℃. It offers the highest chemical resistance and lowest friction but must be tape-wrapped or ram-extruded, making it slightly stiffer.

FEP (Fluorinated Ethylene Propylene): Rated up to 200℃.. It is melt-extrudable, allowing for long continuous lengths and a 20-30% smaller diameter than conventional wires, perfect for tight spaces.

PFA (Perfluoroalkoxy): Rated up to 250℃.. It combines the superior extreme-heat rating of PTFE with the extrusion flexibility of FEP.
