Rubber tires are an indispensable component of modern transportation, and white carbon black plays a magical role in them, greatly improving the performance of tires.


Traditional tires mainly use carbon black as a reinforcing agent, but with the continuous improvement of tire performance requirements, white carbon black is gradually emerging. White carbon black has a unique microstructure, with a large number of silicon hydroxyl groups on its surface. These hydroxyl groups can form chemical bonds and physical adsorption with rubber molecules, thereby forming a three-dimensional network structure in rubber, significantly enhancing its strength and wear resistance. Compared with carbon black, rubber reinforced with white carbon black performs better in terms of wear resistance, effectively reducing tire wear during driving and extending tire service life.


The anti-skid performance is one of the important indicators of tire safety. On damp roads, the friction between the tire and the ground decreases, which can easily lead to slipping. The addition of white carbon black can change the microstructure of the tire surface, increase the contact area and friction between the tire and the ground, improve the grip of the tire on wet and slippery roads, and greatly enhance driving safety. Research has shown that tires reinforced with white carbon black have significantly shorter braking distances on wet and slippery roads compared to traditional tires.


In addition, white carbon black can also reduce the rolling resistance of tires. Rolling resistance refers to the resistance that a tire experiences in the opposite direction of rolling during the rolling process, which consumes the vehicle's energy and increases fuel consumption. Rubber reinforced with white carbon black has lower hysteresis loss, which can reduce energy loss and thus lower the rolling resistance of tires. This not only helps improve the fuel economy of vehicles, reduce exhaust emissions, meet environmental requirements, but also reduces the operating costs of vehicles.


With the continuous development of the automotive industry, the requirements for tire performance are also increasing. White carbon black, with its excellent performance, has a very broad application prospect in the field of rubber tires, and will make greater contributions to people's travel safety and economic environmental protection.
