Properties      Soluble in carbon disulfide, chloroform, carbon tetrachloride, insoluble in water. No odor, no toxicity. Storage is stable.

 

Uses            Secondary accelerator for NR, SBR, EPDM, and NBR. For rich sulphur content of 28%, it could be used as cure agent. In the system of SBR and NBR.The vulcanization is safe under normal temperature, vulcanized rubber is heat-resistant, aging-resistant. This product can be used as primary accelerator for chlorosulfonated polyethylene rubber, SBR and IIR. Easily dispersed, no contamination. Normally used for the manufacturing of heat-resistant products, cable, etc.
