ECO also known as epichlorohydrin rubber, is based on the side containing chlorine is the main chain of rubber - ether. Has excellent heat resistance, oil resistance, cold weather and ozone resistance, and excellent flame retardant, in the automobile industry, oil industry, the aerospace industry to be widely used, and achieve automobile exhaust emission standards for the use of the higher temperature requirements (operating temperature -40 ~ 140 ° C).
