Rubber Accelerator TMTM (TS)

Rubber Accelerator TMTM, also known as TS or Tetramethyl Thiuram Monosulfide, is a sulfur-bearing organic compound that belongs to the thiuram class of accelerators. It is commonly used in the rubber industry to promote the vulcanization or curing of rubber. Vulcanization is a chemical process that cross-links polymer chains in rubber, leading to improved mechanical properties, such as strength, elasticity, and heat resistance.

Rubber Accelerator TMTM is commonly employed in the production of tires, conveyor belts, shoe soles, and various other rubber products where enhanced mechanical and thermal properties are required. Proper handling and adherence to safety guidelines are crucial when working with TMTM in industrial applications.
