Vulcanization Accelerator. is a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Vulcanization accelerators can be classified as primary and secondary accelerators. Important primary accelerators include thiazoles and sulfenamides.

VULCANIZATION ACCELERATORS. Organic accelerators are mainly used to reduce the reaction time of rubber vulcanization or usage of vulcanizing agent and we are supplying thiuram series with very fast vulcanization speed, sulfenamide series with relatively fast speed, and guanidine series with medium speed.
Common Vulcanization Accelerators
Common Accelerators for Sulfur Vulcanization . A large number of chemicals that belong to different chemical classes are known to accelerate rubber vulcanization. About 50 of these accelerators are used on a commercial scale. Most of these belong to the six classes as described below.

Vulcanization & Accelerators
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
