Thiocarbamyl Sulfenamide is a morpholin-4-yl morpholine-4-carbodithioate.
Acts as a vulcanization accelerator.
Thiocarbamyl Sulfenamide contains 20 wt% polymer binder and dispersing agent.
Thiocarbamyl Sulfenamide is an activator which has great activity above 149°C for high temperature vulcanization.
Thiocarbamyl Sulfenamide is a fast vulcanization rate and long scorching time accelerator for NR, BR, SBR, NBR, etc and its vulcanizate has excellent properties such as high tensile strength, small permanent deformation, low compression heat, good elasticity.
Thiocarbamyl Sulfenamide has excellent vulcanization reversion resistance for high temperature vulcanization of NR.
Combination with benzothiazoles or sulfonamides accelerators can lead to a remarkable synergistic effect and reduce total dosage of accelerators significantly to reduce the cost of rubber mixing.
Thiocarbamyl Sulfenamide is a sulfur donor in effective or ineffective vulcanization system. Used in rubber products.
