The development of China's tire industry is inseparable from the rubber auxiliaries industry, and the development of the rubber auxiliaries industry is also inseparable from the tire industry. Radial tires are the development direction of China's tire industry. Therefore, the development of rubber additives for radial tires is also the development direction of China's rubber additives industry.
By 2005, China's tire production value was about 125 million, during which the radial tire output value reached 56 million, and the tire radialization rate will increase to 45%. It is required that the car tires have a meridional rate of 100%, the light truck tires have a meridional rate of more than 60%, and the truck tires have reached more than 35%. At the same time, China's tire industry is also active in the development of high-function car radial tires, high-performance environmentally friendly tires, engineering radial tires, agricultural radial tires. The development of these new tires is closely related to the use of new raw materials and new rubber additives.
