Application

◆ RXX 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. RXX MBT is a retarder of cure in rubber compounds accelerated using thiurams (TMTD/TMTM) / dithiocarbamates (ZDEC, ZDBC) or ETU class accelerators as main accelerators. Even relatively small dosages of RXX  MBT show significant effect and reduce bloom of thiurams and dithiocarbamates.

◆ RXX  MBT and its combinations with booster accelerators is extensively used in NR, SBR, NR-SB/BR blends, NBR, llR, EPDM and other synthetic rubber based compounds used for the manufacture of motor cycle and scooter tyres, butyl tubes, cycle tyres and tubes, beltings, retreading materials, footwear, hot air cured products, hoses, cables and so on.

Application Notes

Use

MBT-80 is a semi-ultra,multi-purpose accelerator with a plateau curing characteristic,which has retarding effect in CR compounds. It's ideal for foam products and low-hardness products,which can reduce the scrap rate of finished products
