The O class shall be classified as follows: Rubbers in both dry and latex form shall be coded from the chemical composition of the polymer chain using the following classes: Compound numbers or ASTM D specification should also be used in writing a specification to give desired physical property requirements. The M shall be classified as follows: 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.
Retrieved from ” https: All FKMs contain vinylidene fluoride as a monomer. This abstract is a brief summary of the referenced standard. January Learn how and when to remove this template message. The symbols can follow the chemical name for use in later references. A useful overview of different types of FKM-compounds is listed here. For terms related to thermoplastic elastomers, see Practice D 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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 d418.
This page was last edited on 17 Augustat The R class shall be classified as follows: The below table is a list of commonly used rubber polymers used in the sealing industry. Link to Active This link will always route to the current Active version of the standard.
Unsourced material may be challenged and removed. The rubber is classified and coded based on the chemical composition of the polymer chain of the rubber polymer.
For other uses, see FKM disambiguation. FKMs can be divided into different classes on the basis of either their chemical composition, their fluorine content or their crosslinking mechanism. The Q shall be classified v1418 follows: Fluoroelastomers are more expensive than neoprene or nitrile rubber elastomers.
ASTM D is commonly used to designate the correct polymer to be used in rubber compounds listed on material specification or part drawings. Please help improve this article by adding citations to reliable sources.
