A semi EV curing system was applied for studying the effects of nano-sized montmorillonite on rheological and mechanical properties of natural rubber (NR) composites. The montmorillonite as a nano-sized filler which was added into NR at 2.0, 4.0, 6.0, 8.0 and 10.0 parts per hundred rubber (phr). It was found that the montmorillonite functioned as a co-curing agent and reinforcing filler. It decreased the scorch and cure times of the NR composites. The higher the montmorillonite loading, the shorter the scorch and cure times were. It also increased the torque difference, tensile modulus and hardness but decreased the elongation at break. The tensile strength was improved up to an 8.0 phr. of montmorillonite loading.
