Properties
Greyish white or light-yellow powder,granular with slightly odour and nonpoisonous, Specific gravity :1.31-1.34,
Melting point:over 96℃.Soluble in benzene,
methylbenzene,chloroform,carbon disulfide, carbon tetrachloride,methylene chloride,
acetone and ethylacetate;not easily soluble in ethyl alcohol;insoluble in water ,dilute acid , dilute alkali and gasoline.
Application:
CBS(CZ) is an accelerator with high activity and has greatly delayed action, high anti-scorching quality,processing safety and short cure time.Its activity can be reinforced by thiuram and dithiocarbamate type alkaline accelerators.Mainly used in manufacture of tires,rubber shoes,rubber tube,cable and other technical rubber goods.
