A group of materials that are considered waste or previously materials used was used in preparing a group of new samples, and it is important to get rid of such materials by reusing them in new and useful applications. A group of samples was prepared by mixing with a fixed percentage of polyester with different proportions of the dioctyl phthalate (DOP) which is available in large quantities and was used as an unused and waste substance in the petrochemical company in Basrah Governorate because this company stopped working for a long time, with percentages of the waste polymethyl methacrylate ( ws. PMMA) and the shilajit was from the mountains of the Islamic Republic. Six groups (A-F) were prepared according to international specifications by direct mixing method between the materials. The results of the elongation study, Young's modulus, and stress showed very well and some unexpected properties, The highest elongation value in Group F sample 5 was 1.3%, and the highest value for Young's modulus was for Group D sample5 where the value was recorded 292.86Mpa, that added distinctive properties to polyester, which qualifies it for wide industrial uses that require strength and ductility at the same time. results that enable the use of these mixtures in multiple applications such as vehicle paints, construction, piping, protective coatings, composites, storage tanks, and ship materials, which require ductility properties, and high strength.
