The recycling of polymeric materials has been studied in order to save natural resources, mainly from non-renewable sources, in order to minimize the impacts caused to the environment. In this scenario, there are elastomeric materials, such as rubber, mainly used in tire manufacturing, since the pneumatic industry consumes approximately 60% of rubber production. As the final destination of an environmentally correct tire is a requirement, duly supported by national and international laws and regulations, the objective of this work is to develop a study on the efficiency of microwave irradiation in the process of tire powder devulcanization. For this study the tire powder samples were subjected to microwave irradiation, and later incorporated into the polymer matrices of NR (natural rubber) and SBR (butadiene-styrene rubber), and characterized for verification of their properties. For characterization of the samples the following tests were used: Infrared Spectroscopy (FTIR), Hardness, Tensile Strength and Stretching, Rheometry, Swell Index, Thermogravimetric Analysis (TGA) and Scanning Electron Microscopy (MEV). It was verified the technical feasibility of the incorporation of the tire powder in the NR and SBR matrices, since some results showed that the addition of the tire powder irradiated by microwave did not cause significant losses in the mechanical and thermal properties of the compounds.
