Used as a sulfur-containing vulcanization accelerator in the rubber industry, particularly in the production of tires and industrial rubber goods. It promotes efficient sulfur cross-linking during vulcanization, enhancing heat resistance, mechanical strength, and durability of rubber products. Also functions as a multifunctional additive that modifies curing characteristics, reduces scorch time, and improves overall performance in high-stability rubber formulations, including synthetic rubbers like SBR and NBR.
