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.

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.

PACKING & STORAGE:

Net weight 25kg/PE bags lined carton; Net weight 600 kg/pallet.Shelf-life: 12 month in its original packagingStored in a dry and cool place.
