Rubber Accelerators

MBT is a semi ultra fast accelerator for NR, SBR, BR, NBR and other highly unsaturated diene rubbers. It readily disperses in rubber compounds and also acts as a mild peptizer for NR & CR. MBT is a re-tarder of cure in rubber compounds accelerated using thiurams (TMTD/TMTM) / dithiocarbamates (ZDC, ZDBC) or ETU class accelerators as main accelerators. Even relatively small dosages of MBT show significant effect and reduce bloom of thiurams and dithiocarbamates. MBT also acts as a retarder in CR based compounding formulations.
