Molecular Formula: C7H5NS2
Product Standard: GB*******9
CAS NO: *******4
Properties: Light-yellow powder, bitter, nonpoisonous. Specific gravity: 1.***1.*2. Soluble in ethyl. Acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline.
Application: Used accelerator in various rubber products. It is a medium fast primary accelerator for natural and synthetic rubber. Can reinforce the plasticity of natural rubber and can be used along or in combination with other basic accelerators for high activity. Imparts excellent aging properties, when used both alone and in combination with DM, and others, mainly basic accelerators for higher activity. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc.
