In the experimental study, five formulations of PP and LLDPE viz. 95/5, 85/15, 75/25, 65/35 and 55/45 Wt % were prepared for injection moulding machine. Then different tests were carried out such as tensile test as mechanical test and the melt flow index (MFI), Melt density of the blend has been determined as rheological test. Results obtained addition of linear low density polyethylene (LLDPE) to polypropylene in most cases decreased the tensile strength of polypropylene. Also obtained decreasing in melt density of the polypropylene material while melt flow index (MFI) is increased. The results showed improvement on the mechanical and rheological properties of polypropylene . The work recommends the optimum compound provided the good performance of PP/LLDPE blend is (65/35) weight ratio % respectively.
