In the intricate world of rubber compounding, vulcanization accelerators are indispensable. Among them, Rubber Accelerator CBS, chemically known as N-Cyclohexyl-2-benzothiazole sulfenamide, is a highly regarded compound. This article aims to provide a comprehensive overview of CBS, detailing its chemical nature, its role in rubber vulcanization, and why it has become a preferred choice for manufacturers globally. For those looking to buy this essential chemical, understanding its benefits is key.

Rubber Accelerator CBS is classified as a sulfenamide accelerator, a group known for their excellent balance between scorch safety and cure rate. Its chemical structure, C13H16N2S2, with a benzothiazole ring and a cyclohexylamino group, is specifically designed to perform efficiently during the vulcanization process. Typically appearing as an off-white to pale yellow powder, CBS boasts a melting point above 98°C, indicating good thermal stability during processing. Its solubility in various organic solvents facilitates uniform dispersion within rubber matrices.

The primary function of CBS is to significantly accelerate the vulcanization reaction. It acts by promoting the formation of sulfur cross-links between polymer chains in rubber. What distinguishes CBS is its 'delayed action' characteristic. This means that under typical processing temperatures, the accelerator remains relatively inactive, providing a crucial 'scorch safety' period. This extended scorch time allows manufacturers to safely mix, shape, and process the rubber compound without fear of premature curing. Once the rubber reaches the desired curing temperature, CBS rapidly initiates the vulcanization process, leading to a shorter overall cure time.

The benefits of using Rubber Accelerator CBS are manifold:

  • Enhanced Processing Safety: Superior scorch resistance prevents premature vulcanization, allowing for flexible manufacturing schedules.
  • Efficient Curing: Shortens the time required for vulcanization, boosting productivity.
  • Improved Product Properties: Contributes to higher tensile strength, better elongation, and excellent resistance to aging.
  • Aesthetic Qualities: Minimal discoloration and non-blooming characteristics maintain product appearance.

CBS is widely applied in the manufacturing of tyres for various vehicles, as well as in the production of industrial rubber goods such as hoses, belts, cables, and footwear. Its consistent performance and reliability make it a go-to accelerator for achieving high-quality rubber products that meet demanding performance criteria.
