CSM trade names. Replacements for Hypalon rubber include: Hailon chlorosulfonated polyethylene from Lianda; TOSO-CSM ®, extos ® alkylated chlorosulphonated polyethylene from TOSOH of Japan; A variety of CSM products from Jiangxi Hongrun Chemical Co., Ltd.
Fluoroelastomers or FKM (sometimes also referred to as FKM Viton) can be classified by their fluorine content, 66%, 68%, & 70% respectively. This means that FKM rubber having higher fluorine content, have increasing fluids resistance derived from increasing fluorine levels.
inhibitors). HNBR is also referred to as HSN or Highly Saturated Nitrile. Hydrogenated nitrile is a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR). In this process the molecular “double bonds” in the NBR primary polymer chain undergo a hydrogenation process and therefore the term “hydrogenated nitrile”.
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite). These materials have good abrasion resistance and good aging stability when protected by additives.
Styrene-Butadiene Rubber. Styrene-Butadiene Rubber is most often made up of 25% styrene and 75% Butadiene, which is a higher butadiene content than Styrene-Butadiene Latex and this makes it more elastic-like. SB Rubber’s development traces back to the discovery of synthetic rubber in Germany in the early 1900s.
