APPLICATION:

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.
