Application technology of aramid cord in tire

In 1970s, DuPont Co. developed aramid successfully. Since then, aramid has been widely used in aerospace, mechatronik, construct, auto, sporting goods and other aspects of the national economy because of its excellent performance. There is a large amount of usage in rubber industry, accounting for 20% of total consumption. It＇s mainly used in tire, conveyor belt, hose and other rubber products as reinforcing material. Aramid cord （KEVLAR：）, as a new type of raw materials for tire, has excellent riding comfort, low roiling resistance, light weight, fuel economy, etc. It has been used as the components of radial tire layer ply and matrix layer for the global major tire companies now. As a reinforcing material of radial tire, aramid cord is the development direction.
