FKMs or fluoroelastomers, are a family of elastomers with resistance to a broad range of chemicals combined with very good high temperature properties. Specialty types with differing monomer compositions and fluorine content are tailored for superior fluid resistance, low and high temperature performance, and combinations thereof. FKM is used in various types of products, such as seals, O-rings, gaskets, and hoses, that are widely used in the automobile, chemical, machinery, aerospace, and electronics industries.
