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.
