Virgin PET - PBT and Post Consumer PET -PBT Blends: A Viable Techno Economic Solution for Engineering Thermoplastic Resins

摘要

Polymer blending has been established as the most successful method of the synthesis of entirely new material with the added qualities. Considering the social and environmental obligation the reuse of PET bottle scrap is the peculiar trait in the present study along with the rich blend of virgin PBT and PET. Tensile properties of PET are inherently better, while PBT also has good mechanical properties besides high crystallization rate. The combination of these properties along with the use of reclaimed material in the blend proved to be excellent. Morphological studies show the controlled and well dispersed phases in these blends and through mixing of the constituents is observed in the thermal scanning. The chemistry of the newly formed blend is also similar to that of the virgin materials. Thus an attempt has been made to co-relate the morphology, thermal study, mechanical characteristics and chemistry of the blends and it was observed that this innovation seems to be techno-economically feasible.
