FKM (or FPM by ISO) are elastomers based on fluoro rubbers and have outstanding resistance to heat, weathering and many other chemicals.
SKF Ecorubber-2
SKF Eccorubber-2 is an elastomer based on fluororubber (FPM, FKM), also known as VITON (registered trade name of Du Pont), which can be used for U-cups, lip seals, packings, wipers and special seals. Its outstanding properties include high resistance to heat, ozone, many chemicals and it is all-weather-proof. SKF Ecorubber-2 is compatible with mineral oils and greases containing sulphur, HFD pressure fluids (nearly all phosphate esters and chlorinated hydrocarbons), crude oil and sour gas. SKF Ecorubber-2 is not resistant to anhydrous ammonia, amines, ketones, esters, hot water and low molecular weight organic acids.
