EPDM broad prospects for development and utilization of

Ethylene-propylene rubber (EPR) is a 1980s variety of synthetic rubber in the fastest growing one of its production capacity and consumption second only to polybutadiene rubber and styrene butadiene rubber in the world of synthetic rubber 7 Variety in the first 3. According to the latest data show that in 2005 the world's total ethylene-propylene rubber production capacity of 1,321,000 tons, production of about 950,000 tons. But in 2006 demand is expected to reach 1,013,000 tons, demand in 2008 will reach about 1,181,000 tons.
China is the world's demand for ethylene-propylene rubber of the fastest growing countries in the world. In recent years, with China's automobile industry, construction industry, such as the rapid development of ethylene-propylene rubber substantial increase in demand. In 1999 China's ethylene-propylene rubber of the apparent consumption of 19,700 tons in 2003 to 65,400 tons in 2004 to reach 85,300 tons more than in 2003, an increase of 30.4 percent in 2005 Chronology of view of consumption of 87,200 tons, In 2004 to grow by about 2.2 percent, from 2000 to 2005 timeline view of the average annual consumption growth rate is about 24.4 percent.
Because China's ethylene-propylene rubber output falls far short of the actual production of domestic demand, which had a year from the United States, South Korea and Japan and other countries of imports, and imports were growing trend. In 1999 China's imports of ethylene-propylene rubber is only 14,200 tons in 2003, increased to 45,300 tons, the product of external dependence for 69.27 percent; in 2004 and further increased to 65,600 tons, 76.90 percent for the degree of dependence on external; in 2005 in China EPR's total imports reached 70,000 tons more than in 2004, an increase of 6.71 percent, to reach 80.3% of external dependence, from 2000 to 2005 the average annual growth rate of imports was about 25.04 percent. At the same time, imports, China's ethylene-propylene rubber in a small way in exports, exports in 2003 amounted to 00,300 tons in 2004 to 02,100 tons in 2005, the export volume to 01,800 tons.
In 2005, China's ethylene-propylene rubber consumption structure are as follows: ethylene-propylene rubber for the auto industry's demand for total demand of 42.53 percent, accounting for 10.34 percent of waterproofing membrane, wire and cable accounted for about 8.05 percent, or about oil additives 10.34 percent, accounting for 11.49 percent of polymer modified, the plastic runway about 9.19 percent, or about 8.06 percent in other areas.
China's automobile industry is non-tire rubber sector of the main application. China's automobile industry consumption of ethylene-propylene rubber mainly used for vehicle-heat-resistant hose, automotive sealing tape, rubber car mats, spark plug jacket, white sidewall rubber tires, protective cover, and so on. Polypropylene and ethylene-propylene rubber modified material used in the manufacture of automotive steering wheel, bumper, instrument panel, fender, air ducts, car fans, heat grill and a variety of pipe fittings and so on. With the. In recent years, the rapid development of China's automobile industry, annual output in 2005 reached 6,150,000, ethylene-propylene rubber consumption of about 37,000 tons are expected in 2006 for ethylene-propylene rubber demand will reach about 40,000 tons, demand in 2010 will reach About 75,000 tons.
In waterproofing membrane, the EPR is the use of performance of one of the best in the membrane. At present, China's annual ethylene-propylene rubber waterproofing membrane of about 9,000,000 square meters, the vast majority of high-grade products to be imported. In 2005 the consumption of ethylene-propylene rubber in the area of about 09,000 tons are expected in 2006 for ethylene-propylene rubber demand will reach about 10,000 tons, demand in 2010 will reach about 14,000 tons.
China is expected in 2006 for ethylene-propylene rubber, the total demand will reach 105,000 tons, the total demand in 2010 will reach about 165,000 tons. Although the Jilin Petrochemical Company will be ethylene-propylene rubber expansion of production capacity to 70,000 tons / year, but output and production capacity can not meet the actual needs of production, still need to import a certain number of ethylene-propylene rubber to meet domestic Actual production demand, ethylene-propylene rubber in the development and utilization of our prospects. Production enterprises should continue to expand the scale of production equipment, increase production and achieve large-scale operations, reduce costs. New installations of the scale of production should be 50,000 tons / year. Should also actively develop the domestic market on marketable new varieties, new brands and expanding the area of application. If the resin used in modified, high-grade sponge in areas such as high-Mooney, a high oil-filled, high molecular weight, long-chain branching structure of the peaks and ethylene-propylene rubber, and so on; metallocene catalyst in the positive application of new technologies to speed up the monomers and additives The catalyst made in order to maintain China's ethylene-propylene rubber industry healthy, orderly and rapid development.
