Retrieved from ” https: The rubber is classified and coded based on the chemical composition of the polymer chain of the rubber polymer. There are three established crosslinking mechanisms used in the curing process of FKMs. Rubber needs to be formulated with different ingredients to give its physical properties and processing characteristics. This practice covers a system of general classification or nomenclature for rubber and rubber latices.

This article needs additional citations for verification. They provide additional heat and chemical resistance. November 28th, by John Tranquilli. This abstract is a brief summary of the referenced standard.

FKMs can be divided into different classes on the basis of either their chemical composition, their fluorine content or their crosslinking mechanism.

The symbols can follow the chemical name for use in later references.

Compound numbers or ASTM D specification should also be used in writing a specification to give desired physical property requirements.
