On a previous work, non-vulcanized rubber composites consisting of raw SBR and rubber waste regenerated through Solid State Shear Extrusion were successfully attained. In this work the vulcanization of these composites was investigated through Differential Scanning Calorimetry (DSC) and Oscillatory Disk Rheometer (ODR), determining the temperature and time to the vulcanization occurs. From these results, it was possible to hypothesize about the mechanisms of regeneration and revulcanization involved in the process, which may be useful in the implementation of reuse process. After that the composites were vulcanized through pressing on the same temperature and time determined by the DSC and ODR analysis, respectively. Samples to measure mechanical properties of the composites were cut from the vulcanized plates and analysed by tension test and the crosslink density of the composites was analysed through Flory-Rehner with Kraus correction equation. The DSC analysis showed that the vulcanization peak temperature of the regenerated composites without devulcanization agent (BPO) was the same of the control composition (with non-regenerated waste rubber), while the aided regenerated composites have shown a vulcanization peak temperature 20°C above of the control composition. The t_90 of the composites, obtained with ODR analysis, is equal for the control composition and for the aided regenerated composites, but for the regenerated composites without BPO, the vulcanization took place 7 minutes late. It was possible to obtain composites with regenerated rubber waste with better elongation while the crosslink density was maintained on the same order of the control composite, despite achieving more than 60% of relative devulcanization. Furthermore, it was possible to conclude that the regeneration temperature on the extruder plays a key role to achieve these properties.
