2- mercapto- benzothiazole (mbt) rubber accelerator
mbt is primarily used in the rubber industry as a non-volatile vulcanisation accelerator. mbt reacts with zinc oxide and sulfur to form an activated complex, which leads to cross-linkage via sulfur bridges as a result of the reaction with the long-chain rubber molecules. following vulcanisation, mbt can be bonded in the

2-mercaptobenzothiazole (mbt, benzothiazole-2-thiol, cas 149-30-4) was introduced to rubber production in the late 1940s [1]. it has been marketed under different trade names, including captax, accelerator, mertax, and vulkacit merkapto.

2-mercaptobenzothiazole-derived vulcanization accelerators powder
studies have discovered wide presence of 2-mercaptobenzothiazole (2-mbt) and 2-mbt-derived vulcanization accelerators (mvas) in household dust samples, suggesting that these chemicals may have been pervasive in the environment.
2 mercaptobenzothiazole high quality rubber chemical accelerator,2-mbt is used as a vulcanization accelerator especially in rubber products like car tires, cables, seals, shoes, rubber gloves and toys (baua, 2001; bfr, 2008). therefore, a general possible exposure of the population to 2-mbt can be supposed.
accelerators for tires and rubber products,mbtor 2-mercaptobenzothiazole was the first thiazole to be used commercially in the rubber industry. it is highly reactive and used effectively in applications requiring a good degree of activity at lower temperatures: 142°c (287°f) or below, and in slower curing synthetics. mbt imparts flat curing properties and also imparts good aging
- What is 2-Mercaptobenzothiazole (MBT) vulcanization accelerator?
- 2-Mercaptobenzothiazole (MBT) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. Given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment. Humans can be exposed by dermal, oral, or inhalative routes.
- Is MBT a vulcanization accelerator?
- As a vulcanization accelerator in the rubber industry, MBT may be discharged into the atmosphere in the form of particles during the processing of substances. MBT emission in the air around workplaces has been reported with older, eastern European plants; however, no quantitative data are available.
- What is the odour threshold for 2-Mercaptobenzothiazole (MBT)?
- 2-Mercaptobenzothiazole (MBT) is a crystalline substance with a low solubility in water (117 mg/l at 20C) and a low vapour pressure. An odour threshold in water of 1.76 mg/l has been reported.
- What is mercapto benzothiazole?
- 2-Mercaptobenzothiazole is an organosulfur compound with the formula C6H4(NH)SC=S. A white solid, it is used in the sulfur vulcanization of rubber. The molecule is planar with a C=S double bond, so the name mercapto benzothiazole is a misnomer, a more appropriate name could be benzothiazoline-2-thione.
