Used primarily as an accelerator in the vulcanization of rubber, especially in the production of neoprene and other synthetic rubbers. It helps improve the curing process, enhancing the elasticity, strength, and durability of rubber products. Commonly found in industrial rubber goods such as hoses, belts, seals, and automotive components. Also serves as an intermediate in the synthesis of certain pharmaceuticals and corrosion inhibitors due to its sulfur-containing structure. Its reactivity makes it useful in metal surface treatment and in some polymer stabilization applications.
