Organofluorides Elastomers Materials science Fluoropolymers. Fluoroelastomers are more expensive than neoprene or nitrile rubber elastomers.
Rubber needs adtm be formulated with different ingredients to give its physical properties and processing characteristics. There are three established crosslinking mechanisms used in the curing process of FKMs. This means that just listing these asm should not consider this is the formulation. This page was last edited on 17 Augustat From Wikipedia, the free encyclopedia. This article needs additional citations for verification. The R class shall be classified as follows: The M shall be classified as follows: FKMs can be divided into different classes on the basis of asstm their chemical composition, their fluorine content or their crosslinking mechanism.
Aastm symbols can follow the chemical name for use in later references. Mixtures of rubbers are identified by using the class designations v1418 the types of rubbers in the mixture, with the major component listed first if the composition is known and in alphabetical order if the rubbers are present in equal amounts. Viton is now manufactured by Chemours.
All FKMs contain vinylidene fluoride as a monomer.

The O class shall be classified as follows: For terms related to thermoplastic elastomers, see Practice D Compound numbers or ASTM D specification should also be used in writing a specification to give desired physical property requirements. November 28th, by John Tranquilli. The below table is a list of commonly used rubber polymers used in the sealing industry.

Articles needing additional d1148 from January All articles needing additional references. The Q shall be classified as follows: As we know from our post on rubber compoundsthis is the main ingredient of a rubber compound — but not the only ingredient.
