Product Description
FKM FPM(Foluroelastomer)
Foluroelastomer is very stable and possess exceptional resistance to oxidation, weather, flame, oil, chemical attack and swelling in a wide range of liquids. Fluorocarbon exhibits resistance to a broad range of chemicals combined with very good high temperature properties more so than any of the other elastomers. It is the closest available approach to a universal elastomer for sealing in the use of O-rings and other custom seals over other types of elastomers. FKM can be classified in many subgroups according to:
1. Fluorine content: general type (A—66%), middle fluorine content type (B&GBL—69%), high fluorine content type (F&GF—70%), improving low temperature flexibility type (GLT, GFLT) and excellent resistance to more chemicals and solvents (ETP & FFKM). The higher the fluorine content the better the chemical resistance.
2. Polymer: A—dipolymer, B, F and GF—terpolymer.
3. Cure system: standard FKM compounds are bisphenol cured. FKM compounds with peroxide-cured possess better acid solution resistance than the bisphenol cured.
