Rheological behavior of recycled polypropylene for reuse in the automotive sector

This work shows the study of rheological behavior of a material that recycled materials have been incorporated. The transformation process to be applied is the injection molding. The mix of materials used was of the same nature and have similar viscosities. This mixture provides virgin polypropylene and copolymer polypropylene waste materials. This system is very common in the industry. Then there has been a characterization of the mechanical and rheological characterization of the mixture. This characterization has allowed developing a model to predict the rheological behavior during the process of transformation; this predictive model has been experimentally validated by testing machine filling and use of specific software.
