Environmental pressure in the tires so that the silica in the ratio of increase

In the past, the silica in the tire is to improve the performance of the tires, especially in winter tires as well as to enhance road tires in the wet ground holding capacity. Now in the face and high humidity clinging to continue to push capacity at the same time, reducing rolling resistance in order to meet the requirements of environmental protection industry with sales growth of carbon black has played a certain role.

"In the past, not the tire rolling resistance in the context of a real optimization, and the importance only in clinging to the wet surface and braking distance, but now we are convinced that rolling resistance problems in the future will be even more important." Degussa's fill-the-art Materials and coatings sector undertakings THOMAS HERMANN claim.

Now the tire industry with silica mainly sold to Europe, where almost all the original tire used silica, or even more than half of all births are to replace the use of silica. Some non-tire manufacturer in Europe with the European car manufacturers signed contracts will also be silica technology as an investment. Europe silica tire market is ripe, but in other areas there is still a long way to go. Although the Japanese tire manufacturer in the winter tires in the application of silica has been for many years, but in the summer tires or all-weather tires are not common in the application. In the North American market, consumption is basically silica by the European car tire manufacturer controlled.

German television station broadcast a test, 6 Chinese-made tires and Pirelli tires in the wet and slippery road testing Pirelli tires braking distance of 40 meters (from 100KPH), Chinese-made tires and braking distance of 60 meters.
