This research study analyzes the mechanical properties of the PBT/EVA blend. Made by adding EVA to PBT in specific proportions, the samples used for the analysis will use injection molding. The percentage of EVA added to PBT was 0%, 5%, 10%, 15%, 20%, and 25%, respectively. After pressing, the samples were measured for tensile strength according to ASTM D638 standards. The results obtained are that when the content of EVA is increased, the tensile strength of the mixture decreases gradually.
