As a reinforcing filler, it is ideal for producing green tires and can replace carbon black in tire sidewalls, significantly boosting tear strength and resistance without affecting vulcanization time. Ozone aging resistance is influenced by antioxidant and white carbon black quantities. Adding it to treads enhances anti-cutting and anti-tearing properties, reducing flaking, while silica-filled compounds can lower rolling resistance by 30% compared to carbon black-filled compounds.
