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.

What is MBTs used for?

MBTS is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, MBTS does not split off active sulfur during vulcanization. For use in natural and synthetic rubber processing. MBTS has a higher critical temperature than MBT, preventing early-cure and scorching.

How to analyze MBT in MTBE extracts of sulfur cured rubber?

A LC-MS-MS method was developed analyze MBT in the MTBE extracts of sulfur cured rubber. The method is specific for MBT and it linear over 50 – 1000 ng/mL. The method is reproducible for extractable MBT determination. The percent recovery of MBT is 87.7% at 400 ng/mL level. The DL of MBT is 6 ng/mL or 12 pg on column.

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 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.

How does MBTs work in polychloroprene?
