Vulcanization Accelerators
An accelerator is defined as a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber.

Application: DCBS is a sulfenamide accelerator with excellent anti-scorching property and delayed onset of cure. It is compatible with natural and synthetic rubbers, suitable for radial ply tyre, rubber belts and shock absorber, etc. Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight.

An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanizationand thus improving 'aged' properties of the rubber vulcanizates.

Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C
