When the EU carbon tariff policy approached, tire giants found a magical "white additive" - special white carbon black prepared by the sol gel method, which could reduce the rolling resistance of tires by 22%, while improving the wet grip by 15%. Even more astonishing is that this material continuously releases silanol groups during wear, forming self-healing microstructures. This article provides an in-depth analysis of its dynamic crosslinking mechanism with rubber molecules, as well as breakthrough experimental data in the field of aviation tires.
