Rail transit sealing rubber seal position and role in the field of seal will increasingly improve, demand will be further expanded. The world each big rubber seal products are almost at the Chinese multinational group, nine in the top 10 in China. In the top 50 tire, there are 32 enterprises to build the 62 factory, more than two-thirds have rubber seals production. If including 50 day in the us and Europe and other countries outside of the tire companies in China, now has reached more than 100. Them on the cars and other high-end rubber products production, account for two-thirds of the market dominant position in our country, and has formed a close system interaction between upstream and downstream. In addition, there is in more than 100 to Hong Kong and Taiwan from the mainland non-tire rubber products in the enterprise, there are also a significant part in the production of rubber seals. Now, the world's largest rubber seals production has started outside the non-tire rubber goods multinationals in China's global era.
Automotive sealing strip of rubber material with solid rubber, sponge rubber and three kinds of hard rubber. Rubber is more use of ageing resistance, low temperature resistant, resistant to moisture, resistant to chemical corrosion, especially the resistance to ozone aging EPDM (EPDM). EPDM can with steel belt, steel wire braided belt, TPE, flannelette, flocking, PU coating, organic silicon coating compound, such as to ensure that the car interior with the outside world and itself is waterproof, dustproof, sound insulation, heat insulation, vibration, wear and adornment effect. Generally stable EPDM seals can use more than a decade. Also can choose to have good ozone resistance and good aging resistance of chloroprene rubber (CR). Considering the commonly used process performance of the rubber, sometimes also need to choose and use rubber, such as natural rubber (NR) with CR and styrene-butadiene rubber (SBR) with three kinds of rubber and polyethylene (PE), EPDM or NR rubber type and to improve the ozone resistance.
