The effect of pulverised rice husk (local filler) on the mechanical properties of low-density polyethylene (LDPE) was investigated. The experiment was carried out by measuring and mixing various proportion of pulverised rice husk with a definite (100%) proportion of Low Density Polyethylene in semi-solid form. The results were obtained by conducting the tensile test using the Monsanto Tensometer on the various specimens produced from the experiment. The results show that the pulverised rice husk increases the mechanical strength of low–density polyethylene (LDPE) with useful mechanical properties manifesting at filler values above 4 grams. The 10 grams filler gave the highest stress value of 52.63N/m2,strain values of 0.18, Young’s modulus of 292.38N/m2, and Poisson’s ratio of -0.999999304 while the 12gram filler ruptured at the second stretch. These mechanical properties increased with increase in the filler content because the filler acts as local crystallites thereby increasing the capability of the material to withstand higher stress as a result of increased modulus. In conclusion, the effect of pulverised rice husk on the mechanical properties of low-density polyethylene was found to enhance the tensile properties, tear strength, young’s modulus, and Poisson’s ratio of the polymer and elongation at break was also found to be reduced with increasing filler concentration.
