What is Westco MBTs accelerator for rubber?

WESTCO™ MBTS accelerator for rubber is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, WESTCO™ MBTS does not split off active sulfur during vulcanization. For use in natural and synthetic rubber processing.

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.

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?

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 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.

What is the difference between MBTs and MBT?

WESTCO™ MBTS has a higher critical temperature than MBT, preventing early-cure and scorching. To conduct processing safely, it is recommended that MBTS accelerator be used in combination with basic accelerators such as TMTD. Technical Product Sheets and SDS sheets are available for each of the chemicals listed.
