Evaluation of the effect of the incorporation of rubber tire waste particles on the properties of PP, HIPS and PP/HIPS matrices

In recent years, the consumption of plastics has been increasing and as consequence, the waste generated has also increased. Rubber tire (RT) waste is another residue which causes significant problems to society. In view of the considerable amounts of RT waste generated, this study aimed to evaluate the influence of the incorporation of RT particles into post-consumer thermoplastic matrices such as polypropylene (PP), high impact polystyrene (HIPS) and PP/HIPS blends and the modification of the physical, morphological, rheological and mechanical properties. The particle sizes of the RT used were
