Mixtures of rubbers are identified by using the class designations for the types of rubbers in the mixture, with the major component listed first if the composition is d11418 and in alphabetical order if the rubbers are present in equal amounts. For other uses, see FKM disambiguation. All FKMs contain vinylidene fluoride as a monomer.
