Used primarily as a rubber accelerator in the vulcanization process, enhancing the rate at which sulfur cross-links with rubber polymers. It is especially effective in tire manufacturing, where it contributes to improved tensile strength, elasticity, and heat resistance of the final product. Offers good scorch safety, meaning it delays premature curing during processing, which is critical in high-temperature manufacturing environments. Also used in combination with other accelerators to optimize cure time and performance properties in industrial rubber goods such as hoses, belts, and seals. Shows limited activity as a fungicide in certain agricultural formulations, though this is a minor application compared to its role in polymer production.
