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. Simon Industry Corp. have more high performence FKM rubber than others, like Viton (Trade Mark).
