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.
