Abstract

In general, high mechanical properties such as higher impact strength and thermal resistance are required for injection molded applications. Recycled PET (RPET) is well known to exhibit brittle behavior in the presence of notches and indicated the low heat distortion temperature. Therefore, we tried to improve the toughness and thermal resistance properties of RPET by incorporating E-GMA, talc filler and engineering plastics as an impact modifier and talc to increase the rigidity and heat distortion temperature of RPET. As a result, these blends with E-GMA exhibited significantly higher stiffness and strength especially with increasing E-GMA content. In addition, these blends with talc filler indicated the high heat distortion temperature due to the increase of the crystalinity of RPET blends. Therefore, it was found that talc played an important role in enhancing the heat resistance of RPET.
