Abstract
The Study of the Effect of Eggshells on the Mechanical properties of low density polyethylene (LDPE), which is manufactured in the General state company of petrochemical industries, Basrah, as function of the percentages weight of eggshells (5%, 10%, 15%, 20%, 25%, 50%), at particular size (<125)µm. were investigated through several variables, such as, Young's modules, strength, and elongation. The obtained results were appeared that the added eggshells act to reduce the spaces between the polymer chains, which reflects the high ability of the polymer against the applied stress, the results also appeared that (the stress-strain) curve was a cold drawn type, and a high degree of homogeneity between the host polymer and the added fillers. The percentage of elongation of this polymer decreases gradually as the percentage of these fillers increase the hardness, and this increase will give further property that increase the hardness of the prepared specimens. The increase of the filler percentages show stability at the percentage 40% and 30%, the results lead to that the strength at both break and yield will be affected little till the percentage (30%), and lowered after that with increasing the percentage also indicate an increase in young's modules with percentage of the added filler accept at the percentage 10%, which reflects the increase in the ductile of the polymer grafted with eggshells and wide range of the application for this polymer. The results also appear that the highest point of the stress is (20 N/mm2).
