The present study, regeneration of vulcanized rubber foam waste through Solid State Shear Extrusion (SSSE) had been investigated. Initially, the raw waste was subdued to a Termogravimetry Analysis. Both raw waste and regenerated waste were characterized in terms of soluble content by Sohxlet Extraction and its granulometry classified by sieving. The structure of raw waste, regenerated waste and remaining ashes of raw waste after thermogravimetry analysis were analysed by Scanning Eletronic Microscopy (SEM). The influence of the process temperature on the reclaiming material was investigated using three different temperatures in the extruder: 100°C; 120°C and 140°C. The presence of benzoyl peroxide, a possible devulcanization agent, during extrusion was also studied. The next stage consisted on the study of the incorporation of 40 phr of the regenerated material in random copolymer styrene-butadiene rubber, SBR, along with vulcanization reagents for later vulcanization through two roll mill. The SEM analysis showed that the rubber waste has a cellular closed structure with mineral fillers dispersed alongside the rubber matrix. SSSE method pulverized the rubber from a mean population around mesh 35 to a mean population around mesh 65 and did not broke significantly the main chain of the rubber as showed by the maintenance of sol-gel content after the regeneration. The difference between the three proposed extrusion temperatures did not change the results of the measured properties. From the analysis carried out, it was not possible to infer if the addition of BPO influenced some property of the rubber waste. Non-vulcanized rubber composites consisting of raw SBR and regenerated waste were successfully attained.
