The advantages of green tires over ordinary radial tires are mainly reflected in three aspects: rolling resistance, wetland grip performance, and noise.Improving wetland grip performance and reducing noise are mainly achieved by optimizing pattern design and skeleton materials. The relationship with tire formula It is not too big.The most important way to reduce the rolling resistance of tires is to change the formula of the tire tread rubber. Compared with traditional radial tires, four major raw materials have been newly added, namely polystyrene butadiene rubber (SSBR), rare earth cis butadiene. Rubber (Nd-BR), highly dispersed silica, silane coupling agent. As a key material of the green tire tread rubber formula, high-dispersion white carbon black is an important reinforcing filler. The addition of tread rubber can improve the cut resistance and tear resistance of the tread, and reduce the amount of popping and dropping.
 
It is estimated that in 2015 and 2020, the domestic demand for white carbon black will be 560,000 tons and 1.65 million tons, of which the highly dispersed white carbon black will be 380,000 tons and 1.42 million tons respectively; the global tire demand for white carbon will be 1.67 million. Tons and 3.33 million tons, of which high-dispersion white carbon black was 1.29 million tons and 2.92 million tons, respectively. In 2012, the demand for silica in domestic tires was only 180,000 tons, and most of them were ordinary silica.The demand for highly dispersed silica was less than 40,000 tons; the global demand for silica was only 69 10,000 tons, of which 340,000 tons of ordinary white carbon black and 350,000 tons of highly dispersed white carbon black. This estimate was made at that time in 13 years. The actual situation is that the market demand in 15 years is far from reaching this data. It can be seen that the forecast of industry demand is often unreliable and can only be used as a basis for decision-making.
 
Regarding market space, relevant companies have calculated the market size of highly dispersed white carbon black through publicly available data on the Internet. If according to the present point of time, China introduced tire label related regulations in 2017. If the tire greening rate reaches 70% to 80% by 2020, then the demand for highly dispersed white carbon black in the domestic market will be 120,000 from 2015 to 2020. The ton increased to 650,000 tons. Based on the current average price of highly dispersed white carbon black at 6,000 yuan / ton, the gross domestic market size in 2020 is estimated at 4 billion yuan, and the global scale is around 10 billion yuan.

However, we still need to be cautiously optimistic. In general, the domestic demand for white carbon black will maintain a growth rate of 10%, and the growth rate of highly dispersed white carbon black for green tires will exceed 15%. The future growth of highly dispersed white carbon black is mainly driven by three factors: the increase in the proportion of green tires, the increase in the use of single tires, and the increase in tire output; the increase in the use of single tires and the replacement of ordinary tires by green tires are the growth of highly dispersed white carbon Maximum power.
