FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. All FKMs contain vinylidene fluoride as a monomer. … See more On the basis of their chemical composition FKMs can be divided into the following types: • Type-1 FKMs are composed of vinylidene fluoride (VDF) and hexafluoropropylene (HFP). See more Because of their outstanding performance they find use in a number of sectors, including the following: • Chemical process and petroleum refining, where they are … See more At high temperatures or in a fire, fluoroelastomers decompose and may release hydrogen fluoride.

WebSep 7, 2024 · Fluoroelastomers are a family of fluoropolymer rubbers. FKM is the American standard (ASTM) short form name for Fluoroelastomers or fluoro rubber material. F stands for Fluoro; the K is an abbreviation of the German word Kohlenstoff, meaning Carbon; and the M is the designation of saturated backbone rubber from ASTM. WebApr 27, 2024 · While NBR and FKM have similar chemical resistance, EPDM is completely different. It is incompatible with petroleum (oil and gasoline), but it is compatible with alcohols (ethanol, methanol, and nitromethane), water, coolants (both ethylene and propylene glycol), and glycol-based brake fluid. Of all three rubber types, EPDM is the …
