Traditional tires are reinforced with carbon black, but high rolling resistance leads to increased energy consumption. White carbon black achieves energy conservation through the following mechanisms:


Intermolecular forces: Silicon hydroxyl groups form chemical bonds with rubber molecules to enhance reinforcement efficiency;
Microstructure optimization: Uniform dispersion of nanoscale particles (10-100nm) to reduce stress concentration;
Low hysteresis loss: Energy loss is reduced by 30% -40% during dynamic deformation.
Case: Michelin's "Energy Saver" series tires use highly dispersed white carbon black, which improves fuel economy by 5% and reduces carbon dioxide emissions by 120g/km. With the upgrade of the EU tire labeling law (implemented in 2024), the penetration rate of white carbon black is expected to increase from the current 35% to over 50%.
