Epichlorohydrin rubber

Japanese: エピクロロヒドリンゴム
Epichlorohydrin rubber

It is a type of polyether synthetic rubber, and currently there are two types: epichlorohydrin homopolymer (a) and epichlorohydrin-ethylene oxide copolymer (1:1) (b). Diamines, urea, imidazolines, etc. are used for vulcanization. Homopolymers are flame retardant, have a high specific gravity, and are easy to process. The heat resistance and ozone resistance of the vulcanized material are superior to neoprene, and its oil resistance and solvent resistance are superior to nitrile rubber (acrylonitrile-butadiene rubber). It has lower gas permeability than butyl rubber. It is used in belts, automobile and aircraft parts, and adhesives.
