Abstract :

Polypropylene materials used as bumpers of cars have been examined and compared after several mechanical recycling cycles consisting of alternating cycles of grinding, extrusion and injection. In order to investigate the influence of the recycling cycles on the material, the mechanical properties were studied by tensile testing according to the UNE-EN-ISO-527 standard and Impact testing (UNE-EN-ISO-179). Vicat temperature testing (UNE-EN-ISO-306) and Differential Scanning Calorimetry (DSC) were also performed. After the first recycling cycle the elongation at break and Young´modulus decrease considerably but successive cycles restore mechanical properties. No significant changes were detected in the thermal properties after several recycling cycles.
