INFLUENCE OF SILICA NANOPARTICLES ON THE THERMOMECHANICAL PROPERTIES OF RECYCLED POLYSTYRENE

Polystyrene from packing materials (rPS) was reinforced with 1, 3 and 5 % of silica prepared by the sol-gel method, through a blending process . The thermal, morphological and mechanical properties were compared with those of the virgin polystyrene (PS). The results show that the glass transition te...
