The nanocomposites were prepared using melt intercalation technique in an internal mixer. Particular attention was given to investigate the influence of different processing condition such as rotor speed and mixing time on the tensile properties and also phase morphology of the nanocomposites using SEM. The nanocomposites were prepared from blend of high density polyethylene (HDPE), natural rubber (NR) and organoclay. Significant improvement in tensile strength and modulus of composites were obtained with rotor speed at 80 rpm. While optimum mixing time used was 12 min. The morphology of the composites determined from the fracture surface of tensile specimen showed a large filler particle or agglomeration of organoclay in the blend at low rotor speed. © (2012) Trans Tech Publications, Switzerland.
