Actmix® TBBS-75GE F200

Actmix® Retarder E-80GE F200 is a N-phenyl-N-(trichloromethylsulfenyl)-benzene sulfonamide. Acts as a vulcanization accelerator. It contains 25 wt% polymer binder and dispersing agent. It can lead to long scorching time of rubber compounds, high processing safety and fast vulcanization rate. It can be used alone in low-sulfur vulcanization and can also be combined with dithiocarbamates or thiurams accelerators to improve anti-aging property and modulus of its vulcanizate. Combination with dithiocarbamates and thiurams accelerators can lower vulcanization rate of rubber compounds significantly. Thioureas accelerators have obvious secondary acceleration to TBBS, especially in low-sulfur rubber compounds. TBBS can delay scorching in rubber compounds contained thiols and thiurams accelerators. It is compatible with NR, NBR, AR, SBR, BR, ECO and EPDM. Its addition level for NR is 0.5-1.0 phr with 2.5-3.5 phr sulfur, for SBR is 1-1.4 phr with 0.2 phr thiurams accelerators and 1.5-2.5 phr sulfur.
