Fluoroelastomer or Fluorocarbon Rubber (FKM/FPM) is a synthetic rubber with Fluorine as one of its main constituents. Fluorine content may vary from 65% to 70% depending on the grade selected.

66% Fluorine grades are the most widely used and are Bisphenol Cured. Other grades may be Bisphenol / Peroxide cured.

Fluorocarbon Rubber has excellent high temperature capabilities along with resistance to ozone, weathering, oxygen, many acids, solvents & chemicals.

Special Fluorocarbon grades offer very good low temperature properties.
