The rubber blend is widely used in industry because of its excellent properties. In this study, Nitrile Butadiene Rubber (NBR) was blended with Ethylene Propylene Diene Monomer (EPDM) rubber using montmorillonite as the compatibilizer. Various kinds of accelerator from different accelerator group (DPG, MBT, CBS, TMTD, and ZDEC) were employed into this blend. This research aimed to study the effect of different accelerators on the curing characteristic, mechanical, and swelling properties of the

Meanwhile, TMTD gave the fastest optimum curing time and also the highest torque difference, cure rate index, and rate constant. The other accelerators gave the curing characteristic among them. The MBT gave the highest tensile, elongation, and tear strength. Based on this research, the TMTD, as secondary accelerator, was the suitable accelerator for improving the curing characteristic property and MBT, as primary accelerator, for improving the mechanical properties of NBR/EPDM blend.
