Composites made only with waste-derived fillers had significant lower 300% modulus, tensile strength and hardness than carbon black filled composites (Fig. 4). Nonetheless, composites containing 35 phr of micro sized TP had the highest tensile strength (18.7 MPa) among the 35 phr waste-derived composites, only 12% lower than carbon black composites. In addition, elongation at break of 35 phr micro sized TP was 0.6 times higher than elongation of carbon black composites and very close values of hardness.
