Because of the EPDM rubber has good water resistance and cold resistance and heat resistance of, the construction process and requirements are very simple. Therefore, it is widely used in construction and automobile industry. If more detailed, then there are plastic sports field, waterproof membrane, house doors and windows sealing strip, glass curtain wall sealing, sanitary equipment and piping seals, etc.. Application of EPDM in the construction industry the biggest is the number of plastic sports field and waterproof material, domestic consumption accounted for the total amount of ethylene propylene rubber% - 28% is the appropriate. EPDM production of waterproof coiled material has been gradually replaced by other materials (such as CMS) production of waterproof coiled material, especially for the underground construction of waterproof coiled material.
If the three EPDM maximum application, it is certainly the automobile manufacturing industry. It is mainly used in automobile sealing strip, radiator hose, spark plug jacket, air conditioning hose, rubber pad, rubber hose, etc..
In the sealing strip of automobile industry, the main use of EPDM EPDM rubber elastic, ozone resistance, weather resistance and other characteristics, the ENB EPDM rubber has become the automotive sealing strip body material, domestic rubber annual consumption has more than 1 million tons, but because of the variety, the half according to rely on imports.
Due to the thermoplastic EPDM EPDM / PP intensity is high, flexibility good, high gloss coating, easy recovery and utilization of the characteristic, car bumper and the automobile instrument panel production at home and abroad as the dominant material. Expected to 2010 only two products of the car bumper and dashboard, EPDM/PP domestic annual consumption of up to.
The recycling of such products is mainly used in the process: first remove the product surface coating, crushing, cleaning, and then granulation, adding new materials, the production of new products. This will be able to save a lot of raw materials to achieve better economic benefits in the production of the bumper and the dashboard.
At present, the dosage of EPDM rubber in automobile industry accounted for the total amount of the ethylene propylene rubber 42%-44%, which also does not include ships, trains and container sealing strip of EPDM content. Because the adhesive property of EPDM rubber is not good, in the automobile tire industry in a large number of materials of the tire body and the tread portion to popularize ethylene propylene rubber, only in parts of the inner tube, white wall, tire and use a large number of EPDM rubber.
