Modern industries, including those in construction, increasingly uses various types of polymer materials, which should be characterized by good mechanical properties. In this work, the effect of strain rate (10, 20, and 50 mm/min) on the tensile and properties of three polymers (high-density polyethylene (HDPE), polypropylene (PP), and polyvinylchloride (PVC)) was studied. A twin-screw extruder was used for the preparation of samples. In order to study the influence of strain rate, tensile strength was used. Mechanical property results show that the tensile properties, tensile strength, and elastic modulus increased with the increase in the strain rate, while elongation at the break point decreased.
