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.
