Widely used as a sulfur-containing accelerator in the vulcanization of rubber, enhancing the curing process and improving the physical properties of rubber products. It is especially effective in natural rubber and synthetic diene rubbers, providing excellent aging resistance and tensile strength. Commonly applied in the production of tires, hoses, belts, and other technical rubber goods where durability and heat resistance are critical. Also serves as a corrosion inhibitor and a stabilizer in some industrial formulations.
