Used as a sulfur-containing modifier in rubber compounding, particularly in tire tread formulations, to improve wear resistance and traction. Enhances the interaction between silica fillers and rubber polymers, leading to lower rolling resistance and better fuel efficiency in tires. Also acts as a coupling agent in silica-reinforced rubber systems, improving dispersion and reducing hysteresis. Employed in adhesives and sealants for improved curing and adhesion properties when sulfur-based crosslinking is desired.
