Sulfenamide Pre-dispersed Rubber Accelerator CBS-80

Sulfenamide Pre-dispersed Rubber Accelerator CBS-80 N-cyclohexyl-2-benzothiazolesulphenamide C13H16N2S2 M.W.: 264.4 CAS: 95-33-0 EINECS: 202-411-2 PROPERTIES: Vulcanization accelerator CBS can prolong  scorching time of rubber compounds, high processing safety and fast vulcanization rate. It can be used alone in low-sulfur vulcanization, might as well can be used together with dithio- carbamates or thiurams. Its vulcanizate has excellent properties of anti-ageing and compres- sion set resistance. It can obviously shorten scorching time of rubber compounds together with dithiocarbamates and thiurams. Thioureas have obvious effect on secondary acceleration to CBS, especially in the low-sulfur rubber compounds. It can delay scorching and improve processing safety in thiols and thiurams rubber compounds. DOSAGE: For NR:primary accelerator: 0.5-1.0phr with 2.5-3.5phr sulfur; For SBR: 1.0-1.5phr combine with 0-0.2 thiurams accelerators and 1.5-2.5phr sulfur. TYPICAL VALUES: M…
