CHEMICAL NAME: 2-Mercaptobenzothiazole
MOLECULAR FORMULA: C7H5NS2
MOLECULAR WEIGHT: 167.26
CAS NO.: 149-30-4
PROPERTIES:
MBT is light yellow powder/granule with a little bit osmyl and taste bitter. Density is 1.42-1.52
Soluble in ethyl acetate, ethanol, solution of NaOH and Na2CO3. Insoluble in benzene, water and gasoline. Good storage stability, lower explosion limit is 21g/m3.
APPLICATION:
MBT is used as an acid accelerator currently, and a medium fast primary accelerator. Imparts excellent aging properties when used both alone and in combination with DM, TMTD and many other basic accelerators for higher activity
Its accelerative temperature is low and easily be dispersed with lower pollution.
Mainly used in the manufacture of tyres, tubes, foot wear, rubber belts and hoses etc.
