White carbon black: the 'invisible champion' behind green tires

In the wave of low-carbon transformation in the global automotive industry, "green tires" have become the focus of the market due to their ability to reduce rolling resistance and fuel consumption. In this technological revolution, white carbon black - a seemingly ordinary white powder - is quietly playing a key role.


Traditional tires use carbon black as a reinforcing agent, which can improve wear resistance but significantly increase rolling resistance, leading to increased fuel consumption. White carbon black, with its unique nanoscale porous structure, not only effectively reduces rolling resistance, but also maintains excellent anti-skid performance on wet and slippery roads through the synergistic effect with silane coupling agents. For example, international tire giants such as Michelin have widely used highly dispersed white carbon black in their high-end products, reducing tire rolling resistance by 30% and improving fuel efficiency by more than 5%.


As the world's largest tire producer, China's demand for white carbon black continues to rise. Data shows that in 2023, the consumption of white carbon black in the domestic tire industry will account for over 40%, and the dependence on high-end product imports is still high. With the advancement of the "dual carbon" target, the penetration rate of white carbon black in the tire industry is expected to further increase, becoming one of the core materials for promoting green upgrading in the industry.
