WebMay 19, 2003 · Hexafluoropropylenevinylidenefluoride Copolymers ( FKM ) are a range of fluoropolymer elastomers whose formulation can be tailored to a reasonable extent to … 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. Originally … 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 used for seals, pumps, gaskets and so on, due to their resistance to chemicals; See more • Magnesium/Teflon/Viton • FFKM, perfluoro-elastomers • FEPM, tetrafluoro ethylene/propylene elastomers See more There are three established cross-linking mechanisms used in the curing process of FKMs. • See more Fluoroelastomers provide excellent high temperature (up to 500°F or 260°C ) and aggressive fluids resistance when compared with other elastomers, while combining the most … See more At high temperatures or in a fire, fluoroelastomers decompose and may release hydrogen fluoride. Any residue must be handled using protective equipment. See more • Properties of Elastomers - Chemical Resitancelist (PDF; 0,6 MB) • Designing with Fluoroelastomers (PDF; 0,8 MB) See more
