    Greyish white or yellowish powder/granule with slightly odor and nonpoisonous. Specific gravity: 1.31-1.34. Melting point: over 96°C. Soluble in benzene, methylbenzene, chloroform, carbon disulfide, carbon tetrachloride, methylene chloride, acetone and ethyl acetate; 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, 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 rubber goods. causing no scorches. Vulcanized show excellent physical property and quick complete. Usually used alone, when activated by D, Willing and TS .
