Epichlorohydrin (CO, ECO, GECO)
Hydrin® is the trade name 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.
Sulfur-Cured vs. Peroxide-Cured
ECO are usually Peroxide-cured for standard compounds of GMORS. 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
- The typical applications of epichlorohydrin are fuels or LPG system in automotive.
