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 the common monomer, to which different other monomers are added for specific types and functionalities, fitting the desired application such as hard wearing driver watch straps.

Originally developed by DuPont (under the brand name Viton, now owned by Chemours), FKMs are today also produced by many other companies.
