Used primarily as a sulfur-based accelerator in the vulcanization of rubber, enhancing the speed and efficiency of the cross-linking process. It is especially effective in the curing of natural rubber and synthetic elastomers, providing improved tensile strength and resilience. Commonly employed in tire manufacturing, hoses, belts, and other technical rubber goods where heat resistance and durability are critical. Also acts as a peptizing agent for rubber compounds, aiding in the mastication process during production. Its performance is valued in applications requiring scorch safety and consistent cure rates.
