Thiazoles--Rubber Accelerator MBT(M)
WESTCOâ„¢ MBT Accelerator Mercaptobenzothiazole CAS# 149-30-4. It may be used in non-staining and non-black vulcanizates. It provides anti-scorch protection in sulfurless rubber compounds. It acts as a retarder in CR compounds. Solubility: Soluble in acetone, ether, alcohol, benzene, chloroform, carbon tetrachloride. Slightly soluble in water when mixed with alkalines.
requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C for completion, which is uneconomical by any production standards. The vulcanizates thus produced are extremely prone to oxidative degradation and do not possess adequate mechanical properties for practical rubber applications.

Hard rubber is vulcanized rubber in which 30% to 50% of sulfur has been mixed before heating; soft rubber contains usually less than 5% of sulfur. After the sulfur and rubber (and usually an organic accelerator, e.g., an aniline compound, to shorten the time or lower the heat necessary for vulcanization) are mixed, the compound is usually ...
