All epichlorohydrin rubbers offer low temperatur e 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 Peroxide – 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.
