ISO 1629

ISO 1629, Rubber and latices – Nomenclature is an ISO standard that helps in classification and designation of basic or crude rubber in both dry and latex forms under a series of symbols or signs, based on the chemical composition of the polymer chain. This standardization becomes useful across industry and commerce thereby avoiding conflict in existing trademarks and names.

This standard was originally published in 1976, and was updated in 1987, 1995 (with amendments in 2007 and 2009) and 2013.

Viton

Viton is a brand of FKM, a synthetic rubber and fluoropolymer elastomer commonly used in O-rings, chemical-resistant gloves, and other molded or extruded goods. The name is a registered trademark of The Chemours Company.

Viton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM. This class of elastomers is a family comprising copolymers of hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), terpolymers of tetrafluoroethylene (TFE), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialties. The fluorine content of the most common Viton grades varies between 66 and 70%.

While Viton can be sometimes distinguished from other types of rubber by its often green or brown colour, a more reliable test is its density of over 1,800 kg/m3, significantly higher than most types of rubber (1,010-1,520 kg/m3).
