According to the EU labeling law, from November 2012, all new tires for cars and trucks sold in Europe must be affixed with an energy efficiency label, requiring tire manufacturers to strictly control fuel efficiency, wetland performance and rolling noise. At present, the EU, Japan, South Korea, Brazil, Saudi Arabia and other places around the world have enforced green tire labeling regulations, all of which put reducing tire rolling resistance in the first place, and the key to reducing tire rolling resistance is to rely on changes in the tread rubber formula, that is, to increase the silica content.

The carbonization process for producing silica dioxide involves reacting liquid sodium silicate (water glass) with carbon dioxide to produce silica dioxide (white carbon black) and a waste liquid containing sodium carbonate.

Our company's white carbon black has successfully passed the small batch test of Yokohama Rubber Co.,Ltd.of Yokohama Rubber Co.,Ltd.of Japan.In mid-November,a purchase contract was signed with our company,and the large batch test stage has officially begun.

People have never stopped pursuing the quietness of tires.In the past,due to the loud engine noise,the noise of tires was difficult to detect.But now with the increasing quietness of vehicles and the emergence of electric vehicles,the noise of the vehicle itself has been greatly reduced.This is where the problem of tire noise comes into focus.
