Fkm chemistry
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.
