ABSTRACT

The injection process is a conformation process of thermoplastic polymeric materials that, actually, has a great economic and technologic significance. Its study has supposed a lot of research tasks related with determining the optimal process conditions. On the other hand, the recycled polymeric materials, produced at the end of products life, are an important source of prime materials that can be used for the obtaining of products with a good quality and low costs with respect the conventional products. Resuming both aspects, this study has been dedicated to the material study and modeling, in order to determine the parameters used during the processing. A rheological behavior model of the different blends has been developed that can be calculated from simple laboratory tests, and whose results has been used as a simulation parameter of the injection process.
