1 乙丙橡胶概况 乙丙橡胶是消耗量仅次于丁苯橡胶和顺丁橡胶的世界第三大合成橡胶。 目前,全世界共有10个国家24套装置生产乙丙橡胶,其中采用气相聚合工艺的装置1套,采用茂金属催化剂的装置有2套,总的生产能力为125万吨·年~(-1)。DSM公司是目前世界上最大的EPR生产者,在荷兰、美国、巴西分别拥有3套独资装置,在日本拥有多套装置,生产能力为20.6万吨·年~(-1),占世界总生产能力的20％;Exxon公司是第二大生产厂商,生
1 Ethylene-propylene rubber overview Ethylene-propylene rubber is the world’s third-largest synthetic rubber that is second only to styrene-butadiene rubber and butadiene-butadiene rubber. At present, 24 sets of equipments are produced in 10 countries in the world to produce ethylene-propylene rubber. One set of gas-phase polymerization equipment is used, and two sets of metallocene catalysts are used. The total production capacity is 1.25 million tons. ). DSM is currently the world’s largest EPR producer. It owns 3 sets of wholly-owned equipment in the Netherlands, the United States, and Brazil, and has multiple sets of equipment in Japan, with a production capacity of 206,000 tons per year (-1), which occupies the world’s total production. 20% of capacity; Exxon is the second largest manufacturer, raw
