TOXICOLOGY AND APPLIED PHARMACOLOGY 14, 221-231 (1969) Toxicity of a Rubber Accelerator WALLACE L. GUESS AND ROBERT K. O'LEARY Drug Plastic Research and Toxicology Laboratory, College of Pharmacy, University of Texas at Austin, Austin, Texas 78712 Received April 1, 1968 Toxicity of a Rubber Accelerator.
The two main products are mercaptobenzthiazole (MBT) and mercaptobenzthiazole disulfide (MBTS), a product formed by oxidative coupling of two MBT molecules. The thiazoles are used for the vulcanization of thick articles, and as basic accelerator in EPDM compounds (ethylene-propylene-diene rubbers), in combination with mixtures of ultra .

Significance and Use. 4.1 2-Mercaptobenzothiazole (MBT) is usually the major impurity in MBTS. Free MBT may be determined by this test method. 4.2 MBT and MBTS are used for rubber and latex vulcanization acceleration. The amount of MBT in MBTS may be of importance in predicting performance in rubber compounds and for raw material purchase and control.
MBT can be used as a fast, non-staining accelerator for both dry rubber and latex applications. Low temperature curing can be achieved by the use of TMTD, TETD or DPG as secondary accelerators. MBT confers excellent aging characteristics to vulcanizates.
Slightly foul odour and bitter taste, non-poisonous. Easily soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, soluble in ethyl alcohol, not easily soluble in benzene, insoluble in water and gasoline. The product is a hemi-ultra accelerator, extensively used in vulcanization of natural and synthetic .
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 …
