At present, the domestic EPDM production capacity amounts to 435,000 tons, with 5 manufacturing enterprises in operation; according to incomplete statistics, there are 7 enterprises under construction or planned for construction, bringing the total capacity well above 400,000 tons. The technology originates from abroad, and the advanced production processes as well as catalytic systems are monopolized by foreign countries. The following is a comparative analysis of domestic CPVC catalytic systems and process packages.
