Used as a rubber vulcanization accelerator, particularly in sulfur-cured systems. It promotes efficient crosslinking, improving tensile strength, elasticity, and heat resistance of rubber products. Commonly applied in tires, hoses, belts, and other technical rubber goods where durability and performance under stress are critical. Also helps reduce reversion in thick rubber sections during prolonged curing. Shows good dispersibility in rubber matrices and is often used in combination with primary accelerators for synergistic effects.
