What is MBTs (benzothiazyl disulfide)?

MBTS (Benzothiazyl Disulfide) is a non-staining, primary thiazole accelerator for use in natural and synthetic rubbers. It is very active at temperatures above 280°F. Activation requires the addition of zinc oxide, a fatty acid and sulfur for cure development.

How does MBTs work?

Acceleration: MBTS functions as a primary accelerator, meaning it can initiate and speed up the vulcanization process in rubber production. – Moderate reactivity: It offers a balanced reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends.

Is MBTs a good rubber accelerator?

MBTS is a valuable rubber accelerator with notable characteristics, including acceleration, moderate reactivity, good scorch safety, and excellent vulcanization properties. It finds widespread application in various rubber products, especially in tires, rubber footwear, industrial rubber goods, and automotive parts.

Is MBTs a thiazole?

MBTS is an organic compound belonging to the thiazole class of accelerators. It is a yellowish powder with a slight odor. Chemically, it consists of two benzothiazole rings connected by a disulfide bond. MBTS is known for its high solubility in rubber and various organic solvents, making it an excellent choice for rubber processing. 2.

Is accelerator MBTs available in a polymer bound dispersion?

Accelerator MBTS is also available in a polymer bound dispersion. Several polymer carriers are available. These polymeric masterbatches contain 70-80% Accelerator MBTS and are very soft for ease of incorporation. Akrochem polymer bound dispersions eliminate irritating dust, as well as other potential hazards in handling powders in the plant.

How is MBTs used in a polychloroprene cure system?

Activation requires the addition of zinc oxide, a fatty acid and sulfur for cure development. Secondary accelerators used in conjunction with MBTS such as aldehyde amines, dithiocarbamates, guanidines, and thiurams will increase cure rates. MBTS is also used as a retarder in polychloroprene cure systems, as well as a retarder for peroxide cures.
