Mechanical properties of PE-PET-PS-PP blends produced by high shear mixing

Abstract

This work focused on mechanical behavior of polymer by implementing high speed mixing (HSM) method of polymer blending. In this study, polyethylene (PE), poly(ethylene terephthalate) (PET), polystyrene (PS), and polypropylene (PP) were used as they are the most abundant polymers used at the current time. The research was carried out using counter rotating twin screw extruder at constant speed of 249 rpm and at 120 °C with weight mixing ratio of the plastics are 1 : 1 : 1 : 1. According to tensile study, stress strain curve of the HSM sample exhibited an alloy-like characteristic. With references to other type of virgin polymers and some polymer blends the yield stress, Young's modulus and strain rate of high-speed mixing were quite comparable to the other samples.
