TMTM (CAS 97-74-5), or Bis(dimethylthiocarbamyl) sulfide, is a non-staining rubber accelerator primarily used in the vulcanization of natural and synthetic rubbers. It is a thiuram class accelerator known for its medium-fast curing speed and excellent heat-aging properties. TMTM is widely used in combination with other accelerators to enhance performance, improve processing, and achieve high-quality rubber goods.
Primary or Secondary Accelerator – Used in NR, SBR, NBR, EPDM, and IIR rubber compounds
Vulcanizing Agent – Improves cross-linking density and speeds up the vulcanization process
Non-Blooming & Non-Staining – Ideal for light-colored rubber products and technical rubber articles
Used in the production of tires, inner tubes, hoses, and conveyor belts
Suitable for shoe soles, rubber seals, gaskets, molded rubber parts, and belting
