PHYSICAL & CHEMICAL PROPERTIES OF
RUBBER ACCELERATOR MBTS (DM)
A compound, usually organic, that greatly reduces the time required for vulcanization of natural and synthetic rubber; at the same time, improving the ageing and other physical properties. The major types Include amines, guanidines, thiazoles, thiuram sulfides, and dithio-carbamates.

Gray-white (granule) with a little bittle bitter, no poison, The density is 1.45-1.54 Soluble in chloroform, partly soluble in benzene, ethanol, CCl 4, insoluble in gasoline, water and ethyl acetate. Good storage stability.
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 usually required for synthetic polymers, Better scorch safety than WILLING MBT.
