Used as a rubber vulcanizing agent, particularly in high-performance elastomers requiring improved heat and aging resistance. Offers consistent crosslinking in tire treads and industrial rubber goods, enhancing durability and mechanical strength. Also employed in specialty polymers where controlled sulfur release is critical. Shows lower tendency to generate nitrosamines compared to conventional accelerators, supporting safer manufacturing practices. Suitable for use in low-sulfur or sulfur-free formulations due to efficient disulfide bond activation.
