Tetrafluoroethylene Propylene Polymer
Most commonly known as AFLAS® or Viton® Extreme™; Tetrafluoroethylene Propylene (FEPM or TFE/P) is a fluorinated rubber. It has excellent resistance to a wide variety of chemicals, both acids and bases. It works well at elevated temperatures and has very good resistance to petroleum fluids.

The raw material cost for Aflas® is relatively high and it is difficult to process. Like most other fluoropolymers, AFLAS® does not have especially good low temperature properties

The temperature range for compounds is 0º to 475º F (-15 to 245ºC). PAI offers FEPM compounds in a hardness range of 70 to 90 durometer. Black is the standard color, but some others are available.
