Abstract

This project aims to develop and evaluate the technical viability of blends of recycled PET - (PETr) - and polycarbonate (PC), using chemical compatibilization in a continuous extrusion process. The objective for obtaining these blends is to take advantage of the individual characteristics of their components in a single material. In PC, the characteristics would be resistance to impact and good temperature performance and, in PET, stiffness and chemical resistance. Since PET is a post-consumption material and recycled from carbonated drinks packaging, it would be characterized as technological innovation, which would result in an excellent cost-benefit relationship for the product. The material to be developed could be used in engineering, in direct replacement for other thermoplastics and other blends such as polyamide (nylon), ABS, ABS/PC, PBT/PC and others, in injection processes in technical parts in the automobile industries, in hermetic compressors, in household appliances and electroelectronics. In preliminary contacts with the automobile industry, the need to use quality recycled materials in their products was emphasized.As yet there is no national supplier meeting the technical requirements of the material at a suitable cost.
