A. Replace organic non-renewable carbon black with inorganic renewable white carbon black to reduce the consumption of earth resources by tire production;

B. With the increase of usage of silica, the performance of the tire has also been greatly improved: the rolling resistance is reduced, and the energy saving effect of about 5% can be realized; the improvement of the wet skid performance of the tire surface can shorten the the braking distance on wet roads and the improvement of the safety performance, which are all inseparable from the increase in the proportion of silica, Therefore, highly dispersed silica came into being.
