CHEMICAL STRUCTURE: 
CHEMICAL NAME: Mercaptobenzothiazole disulfide
MOLECULAR FORMULA: C14H8N2S4
MOLECULAR WEIGHT: 332.50
CAS NO.: 120-78-5
PROPERTIES:
DM is gray-white or light yellow powder/granule with a little biter, no poison. Density 1.45-1.54.
Soluble in chloroform, partly soluble in benzene, ethanol, CCI4.
Insoluble in gasoline, water and ethyl acetate. Good storage stability.
APPLICATION:
Given flat moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining and non-discolouring in “white” socks.
Used as a plasticizer and retarder in polychloroethylene rubber. Secondary acceleration is usualy required for synthetic polymers.
Better scorch safety than MBT.
