MBT, the chemical name is 2-Mercaptobenzothiazole.
Structure:
MBT is a primary accelerator for natural and synthetic rubbers with excellent low temperature curing properties. It may be used in non-staining and non-black vulcanizates. It provides anti-scorch protection in sulfur less rubber compounds. It acts as a retarder in CR compounds. Impart excellent aging properties when used both alone and in combination with DM, TMTD and many other basic accelerators for higher activity. Its vulcanizing temperature is low and easily be dispersed with lower pollution. Mainly used in the manufacture of tires, tubes, foot wear, rubber belts and hoses etc.
Solubility: Soluble in acetone, ether, alcohol, benzene, chloroform, carbon tetrachloride.
Slightly soluble in water when mixed with alkaline.
Why the MBT is most popular product in rubber additives? Because of its wide range of applications, it can be used for almost all other rubber products except for the manufacture of rubber products that are in contact with food.
