Fluorocarbon Rubber (FPM / FKM / Viton™)

Fluorocarbon elastomers are commonly referred to as Viton®, FKM and FPM. They are highly fluorinated carbon-based polymers which were developed to provide a material with outstanding physical and mechanical properties when subjected to harsh chemicals and elevated temperatures. Viton® was the original Fluorocarbon elastomer and became a significant material for the sealing industry in the late 1950’s when it was introduced for high performance applications in the aerospace industry by Du-Pont™.

Since then, Fluorocarbon elastomers (FPM / FKM / Viton®) have advanced significantly and are now available in a number of various compounds to help satisfy the most arduous of applications. The elevated temperature capability and chemical resistance of the material is provided by the bulk of the fluorine atoms which shield the polymer backbone and fluorine-carbon bond from attack.

In general terms, the higher the fluorine content the compound contains, the greater the chemical resistance of the compound will be. However an increased Fluorine content will have a direct impact on the materials low-temperature flexibility.

DMR Seals offers a broad portfolio of high quality Fluorocarbon elastomers (FPM / FKM / Viton®) to cope with the most demanding applications, operating in temperatures from -40 to + 210. Our materials are offered in a number of colours and shore hardnesses for you to consider.
