Epichlorohydrin(CO,ECO,GECO)
Hydrin is the trade nme of epichlorohydrin elastomers made by Zeon Chemicals.epichlorohydrin elastomers are available as a homopolymer(CO),copolymer(ECO,GCO),and terpolmer(GECO).All epichlorohydrin rubbers offer low temperature flexibilities;resistance to oils,fuel and common solvents;higher temperature resistance than NBR;good weather ability and good dynamic properties.
Cure system-Sulfur-Cured vs.Peroxide-Cured
ECO are usually Peroide-cured for standard compounds of GE Mao.It also can be Sulfur-cured to improve flexible property in dynamic system but will reduce the heat resistance and cause poorer compression set.
Other Common Variations
