Physical Properties: Black powdery substance that imparts higher tensile strength, tear strength, abrasion resistance, and aging performance to rubber. Used in tire treads, it significantly improves tire wear resistance and puncture resistance.

Applications: Widely used in high-grade rubber products, its versatility is second only to high abrasion furnace black. Primarily used in tire tread rubber, it is often combined with high abrasion furnace black in heavy-duty tire treads. It is also used in large conveyor belts, covering rubber for transmission belts, and wear-resistant rubber rollers.
