FEP (Fluorinated ethylene propylene) is a modified category of PTFE. It remains basically the properties of PTFE, like excellent high- low-temperature resistance, chemical stability, dielectricity, high non-adhesiveness and mechanical strength. Compare to PTFE, it has better elasticity and transparency and is only 50 lower than PTFE by limit of high temperature resistance.
