Main uses: Because the main chain of the ethylene propylene rubber molecule is saturated structure and presents excellent weather resistance, ozone resistance, electrical insulation, low compression permanent color, high strength and high elongation and other valuable properties, its application is extremely wide, the consumption increases year by year. According to the different series of ethylene propylene rubber and the characteristics of the molecular structure, ethylene propylene rubber application type has a general-purpose, mixed type, fast vulcanization type, easy to process and diolefin rubber and other different types of applications. From the actual application of analysis, ethylene propylene rubber in the non-tire has been widely used.
1. Automotive industry, ethylene propylene rubber in the automotive manufacturing industry, the largest application, mainly used in automotive seals, radiator hoses, spark plug jacket, air conditioning hoses, mats, hoses and so on. In the automotive sealing industry, the main use of EPDM elasticity, ozone resistance, weather resistance and other characteristics of its ENB-type EPDM rubber has become the main material for automotive seals, the annual domestic consumption of raw rubber has exceeded 10,000 tons, but because of the relationship between the species, half of which still rely on imports. Due to the thermoplastic EPDM/PP rubber EPDM/PP high strength, good flexibility, high gloss coating, easy recycling characteristics, at home and abroad in the production of automobile bumpers and automobile instrument panels have been used as the leading material. It is expected that by 2010 only two products of automobile bumper and instrument panel, the annual domestic consumption of EPDM/PP can reach 45,000 tons. Recycling of such products is mainly used in the process: first remove the product surface coating crushed and cleaned and then granulated to add new materials to produce new products. So in the bumper and instrument panel production, you can save a lot of raw materials to achieve better economic benefits. At present, China's ethylene propylene rubber in the automobile industry accounted for 42% of the total amount of ethylene propylene rubber - 44%, which does not include ships, trains and container seals ethylene propylene rubber dosage. Because of the poor adhesive properties of ethylene propylene rubber, in the automobile tire industry in a large number of materials used in the main body of the tire and tread parts can not promote the use of ethylene propylene rubber, only in the inner tube, white sidewalls, tire strips and other parts of a small amount of use of ethylene propylene rubber.
2. Construction industry due to the excellent water resistance, heat and cold resistance and weather resistance, but also has the construction of simple and other characteristics, so ethylene propylene rubber in the construction industry is mainly used for plastic sports fields, waterproofing rolls, housing door and window seals, glass curtain wall seals, sanitary equipment and pipeline seals and so on. Ethylene propylene rubber in the construction industry, the largest number of plastic sports field and waterproofing membrane, the domestic use of ethylene propylene rubber has accounted for the total amount of 26% -28%. With EPDM production of waterproofing membrane has gradually replaced other materials (such as CMS) made of waterproofing membrane, especially for underground construction of waterproofing membrane.
3. Electrical and electronics industry in the electrical and electronics industry, the main use of ethylene propylene rubber's excellent electrical insulation, weather resistance and corrosion resistance, in many electrical components in the use of such rubber. For example, the production of cables with ethylene-propylene rubber, especially submarine cables with EPDM or EPDM/PP instead of PVC/NBR production of cable insulation, cable insulation and service life has been greatly improved. In the transformer insulating pads, electronic insulation sheaths are also used in large quantities of ethylene propylene rubber production.
