Fluorinated ethylene propylene (FEP) is very similar to polytetrafluoroethylene (PTFE) in its chemical inertness, dielectric characteristics, coefficient of friction, and high-heat resistance. FEP also sports high stress-crack resistance.

It has a maximum recommended use temperature of nearly 400 degrees F (204 degrees C). Applications that have made use of FEP include lining for pipe and chemical processing equipment, those and tubing for hydraulic and oxygen systems, and many wire and cable applications.
