Used as a rubber vulcanization accelerator, particularly in sulfur-cured systems. It promotes efficient crosslinking, improving tensile strength and elasticity of rubber products. Offers good scorch safety during processing and is effective in tire treads, hoses, and belts. Also acts as a secondary accelerator when combined with primary accelerators like sulfenamides, enhancing cure rates without premature vulcanization. Shows favorable aging properties and resistance to reversion in thick rubber sections.
