About 70 percent of white carbon black used in the production of tyres and other rubber products, so the pace of development depends primarily on the development of silica pace car, tyre and rubber industry. With radial tyres, green energy and comfort requirements are high, white carbon black used in tyres has become increasingly important. At present, the request to reduce rolling resistance and improve grip performance, silica and carbon black exhibits excellent performance with, and in the formula have all alternative carbon black production of "green tyre" white carbon black. In recent years, precipitated silica has been widely used in snow tyres, skid tyres and green tyres. tyres are precipitated silica second largest consumer users, their consumption accounts for about 16% of total consumption.

 

     In recent years, with the rapid development of China's automotive industry and road transport, all kinds of tyre demand will rapidly. In 2007, the domestic tyre production was 330 million (not including motorcycle tyres, the same below), an increase of 17.8%, including radial tyre production reached 230 million, an increase of 28 percent, was 69.7 percent meridian; 2008, tyre production was 350 million, an increase of 6.0%, which radial tyre production was 263 million, an increase of 14.3%, the rate reached 75 percent meridian. At present, the European Green tyre penetration has reached 90% of the domestic formulation research has also started, in view of the safety of people and the growing importance of energy saving, "green tyre" will be the development trend of the tyre industry.

 

     National publication "tyre industry policy" clearly stated that "encourage the development of environmentally friendly rubber chemicals and specialty carbon black, silica and other raw materials," the content, with the introduction of a series of national plans and policies, as well as China's automobile and tyre industry sustained and rapid development, precipitated silica production capacity, production and demand will continue to grow.

 

     Precipitated silica according to application-related industry trends, the next few years, Chinese black precipitated silica demand will average about 10% growth rate, which the tyre industry demand will have faster growth. With the capacity and technology has improved, domestic precipitated silica product quality has to meet the basic needs of the domestic and foreign markets, but the current excess production capacity trends have emerged, the future focus of development is not new or re-scale production plant , but to further enhance product quality, reduce production costs, research and development of high value-added products to reduce imports to meet domestic market demand.

 

     2015, 2020, respectively, the domestic demand of silica tyres at 56 million tons, 1.65 million tons, of which highly dispersed silica, respectively, at 38 million tons, 1.42 million tons; the global tyre demand of silica at 1.67 million, respectively, tons, 3.31 million tons, which were highly dispersed silica at 1.29 million tons, 2.92 million tons. And in 2012 the domestic tyre demand is only 180,000 tons of silica, but most are ordinary silica, highly dispersed silica demand is less than 40,000 tons; global demand for only 69 of silica tyres tons, including 340,000 tons of ordinary silica, highly dispersed silica demand for 350,000 tons.

 

     With the advent of the era of green tyres, high dispersion silica demand will grow by leaps and bounds presented, especially the development of China's green tyres will cause tyre silica accounts around the world to increase the proportion of 25.54% from 2012 to 2015 33.49% year, 2020 of 49.64%, highly dispersed silica cent of the world's proportion of 11.03% from 2012 up to 2015 of 29.46%, 48.55% in 2020. In short, the tyre with silica future market potential, including a highly dispersed silica tyre development potential is far greater than ordinary white carbon black for tyres, tyres with highly dispersed silica, the market potential semi-steel tyres are far bigger in steel tyre.

 

     2012, tyres accounted for 15.35% of silica silica production, and the high dispersion of 3.36% for tyres only silica silica production; 2015 accounted for silica tyres silica production will reach 38.6%, while for the tyre highly dispersed silica will account for 26.27% silica production; by 2020 the proportion of silica tyre silica production will reach 63.21%, the high dispersion for tyres account for 54.51% silica silica production.
