Today, in the framework of environmentally-sensitive production methods and the efficient use of natural resources and energy, new products are needed to reduce the emissions that lead to climate change. Plastic materials play an important role in our daily lives. Polypropylene (PP), a thermoplastic polymer material, has very broad uses such as the automotive industry, textile and food packaging, but in some cases it is unable to provide the desired features. Composite materials are needed to improve the properties of these materials. Composite materials, which are in constant development and change, have many advantages such as reducing costs, improving the product’s efficiency and quality. Some materials used as a contribution to plastic materials, as plastic composite, also produce improvements in mechanical and thermal properties. In this study, a commonly used polypropylene (PP) material with 1% graphite material and a homogeneous mixture in the double-wire extruder plant, 100 standard test bars were produced in the injection machine. The prototype of the product and the composite product with non-added polypropylene (PP) has been tested with isod shock, erosion flow index (MFI), heat deformation test (HDT), hardness test (Shore-D), drawing test and intensity test. According to the test results, changes in some thermal and mechanical properties of the composite material have been studied by non-added polypropylene (PP) and graphite-added polypropylene (GPP). As a result, the mechanical properties of these two materials occurred at approximately 30% and thermal properties improved at approximately 15%. With the improvement of its mechanical and thermal properties, it will provide great advantages in the plastic industry. It is also predicted that it will be used as a new product in the defense industry, aviation and automotive industry.
