b. We can produce products according to customer requirements.


c. Foreign matter entering is completely eliminated.


5. Property
Off-white or light yellow powder or granule, slightly smelly, non-toxic, specific gravity of 1.31-1.34, melting point above96℃; soluble in benzene, toluene, chloroform, carbon disulfide, dichloromethane, acetone, and ethyl acetate, not readily soluble in ethanol, Insoluble in water, dilute acid, dilute alkali and gasoline.


6. Use
CBS is a highly active aftereffect accelerator. It has excellent scorch resistance and it is safe to process. Vulcanization time is short. Alkaline accelerators, such as thiuram and disulfide carbamate, can enhance its activity. CBS is mostly used to manufacture tires, rubber tubes, rubber shoes, cables, and other industrial rubber products.
