MBTS (2,2'-Dibenzothiazyl Disulfide), also known as Accelerator DM, is a widely used thiazole-based rubber vulcanization accelerator for natural and synthetic rubber compounds. It offers excellent processing safety, stable curing performance, and good compatibility with a broad range of elastomers. MBTS is commonly employed as both a primary and secondary accelerator in sulfur curing systems, providing reliable vulcanization characteristics and consistent product quality. MBTS is extensively used in the manufacture of tires, tubes, conveyor belts, hoses, footwear, industrial rubber goods, seals, gaskets, and molded rubber products. Its delayed-action curing behavior helps prevent premature vulcanization during mixing and processing while ensuring efficient crosslinking during the curing stage. The product is typically supplied as a cream to pale-yellow powder, granules, or pellets and demonstrates excellent dispersion in rubber compounds. MBTS contributes to improved tensile strength, abrasion resistance, elasticity, and overall durability of finished rubber products. It is frequently used in combination with accelerators such as TMTD, DPG, or CBS to optimize scorch safety, cure rate, and final mechanical properties. As one of the most established accelerators in the rubber industry, MBTS is valued for its balanced curing characteristics, processing reliability, and versatility across a wide range of technical rubber applications. It remains a standard component in high-quality rubber formulations where consistent performance and manufacturing efficiency are essential.
