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.
