Abstract [en]

There has been an increase over the past decade on electrical and electronic equipment (EEE) production due mainly to the intensification in the use and upgrade of this equipment, and therefore there has been an increase on the disposal of the products after its end of life on landfills. 

This thesis aims to analyze the possibility to blend polymers found in different electronic equipment waste materials in order to evaluate their reincorporation into the market. In order to analyze this possibility, it was necessary to characterize thirty three different electric and electronic waste equipments after the service life of the products. The polymers in these samples were identified by using analytical techniques such as Differential Scanning Calorimetrry (DSC) and Fourier Transform Infrared Spectroscopy (FTIR). Once identified the material composition of this materials, a blend was made with the higher percentages in mass of material given by the analytical techniques to simulate an industrial mixture. These blends were later analyzed by DSC, FTIR, Scanning Electron Microscopy (SEM) and tensile testing in order to evaluate the blends mechanical, chemical and physical properties.
