November 28th, by John Tranquilli.
For other uses, see FKM disambiguation. This means that just listing these nomenclatures should not consider this is the formulation.
Fluoroelastomers are more expensive than neoprene or nitrile rubber elastomers. ASTM D is commonly used to designate the correct polymer to d148 used in rubber compounds listed on material specification or part drawings.
The symbols can follow the chemical name for use in later references. FKMs can be divided into different classes on the basis of either their chemical composition, their fluorine content or their crosslinking mechanism.
ASTM D – 01 Standard Practice for Rubber and Rubber Latices-Nomenclature
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. A useful overview of different types of FKM-compounds is listed here. All FKMs contain vinylidene fluoride as a v1418.
Articles needing additional references from January All articles needing additional references. This article needs additional citations for verification. The M shall be classified as follows: 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 known and in alphabetical order if the rubbers are present in equal amounts.
The rubber is classified and coded axtm on the chemical composition of the polymer chain of the rubber polymer. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This abstract is a brief summary of the referenced standard.
The below table is a list of commonly used d418 polymers used in the sealing industry. Unsourced material may be challenged and removed. Rubber needs to be formulated with different ingredients to give its physical properties and processing characteristics. From Wikipedia, axtm free encyclopedia. They provide additional heat and chemical resistance.

The R class shall be classified as follows: This page was last edited on 17 Augustat Please help improve this article by adding citations to reliable sources. Compound numbers or ASTM D specification should also be used in writing a specification to give desired physical property requirements.
This practice covers a system of general classification or nomenclature for rubber and rubber latices.
Rubbers in both dry and latex form shall be coded from the chemical composition of the polymer chain using the following classes: Link to Active This link will always route to the current Active version of the standard.
Viton is now manufactured by Chemours. List of Rubber per ASTM D The rubber is classified and coded based on the chemical composition of the polymer chain of the rubber polymer.
