Currently, the use of additives from renewable sources in elastomeric composites became an object of study, since these products have less impact on the environment. In this study, three compounds from renewable sources were used in an elastomeric formulation with application in bus body rubber profiles technology. We used soybean oil (MD600), a curing activator (MDECR) derived from sugar cane and loading filler (MDCO) derived from cereals to replace components traditionally used at rubber industry in a formulation with terpolymer of ethylene-propylene-diene (EPDM). A standard composite of bus body rubber profiles and nine composites with varying proportions of MDECR (3, 4 and 5 phr), MD600 (10, 15 and 25 phr) and MDCO (10, 30 and 50 phr) were prepared.The technical performance was evaluated by analyzing the physical-mechanical properties (tensile and tear strength, shore A hardness) of all obtained composites. The composites with best results of MD600, MDECR and MDCO were submitted of accelerated aging in an air oven (thermo-oxidation). The results of the rubber composites were compared with a standard composite prepared with conventional additives used in rubber industry. The physical-mechanical properties showed that the best performance was achieved by the composites containing 4 phr of MDECR and 10 phr of MD600, promoting a 75% and 60% reduction of zinc oxide and oil content, respectively. For the composites with MDCO (30 phr) the physical-mechanical properties were not affected, since it is a loading filler. Finally, the physical-mechanical properties of the composites were not affected by the accelerated aging process.
