    Resumen:
    This article proposes the creation of a new material useful for the industry from the mixture with rolls of two 50% virgin elastomers, styrene-butadiene (SBR) and natural rubber (NR) with tires out of use (GTR). These tires have been previously devulcanized following a number of techniques, which will be analyzed in this article, and then mixed with the virgin elastomer SBR/NR and the corresponding additives, revulcanized this new material in order to reach the mechanical properties , Thermal and of structure that allow its use in the industry. Specifically, three types of samples have been analyzed; a first one formed by the virgin elastomer (SBR/NR), a second adding to the SBR/NR, GTR in the proportion of 20 phr (parts per hundred rubber), and a third adding to the SBR/NR, GTR in the proportion of 40 phr (more percentages were used in the mechanical tests in order to provide greater validity in the results). The GTR received has been devulcanized using different techniques: without devulcanitation (dn); mechanically devulcanized (dm); chemically and mechanically devulcanized (dcm); and microwave devulcanized (dmw). All these compounds have been tested with different tests; Mechanical, Crisscrossing Density, Gravimetric Thermal Analysis and Microscopy Test.
