FEP ( Fluorinated Ethylene-Propylene) is the softest and most flexible of the fluoropolymers. It is the preferred choice for long length requirements and with excellent electrical properties (stable over changing frequencies and temperatures), this makes it an ideal choice for use in data cables and coaxial.
PFA (Perfluoro alkoxy alkanes) shares many of PTFE’s exceptional properties but with the added benefit that it can be processed by normal means, allowing for longer lengths and larger sizes that are possible with PTFE.
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. PTFE is unique amongst the fluoropolymer materials as it processed by either cold ram-extrusion or tape-wrapping and is then sintered at high temperatures to set the material.
