Recently, researchers have shown an increased interest in materials treatment in order to improve the characterization and thermal properties of composite. In this paper, the effect of recycled acrylonitrile butadiene rubber (NBRr) loadings and compatibilization of polypropylene maleic anhydride (PPMAH) in the polypropylene (PP) / recycled acrylonitrile butadiene rubber (NBRr) / banana skin powder (BSP) composites were studied. The composites for both uncompatibilized and compatibilized polypropylene maleic anhydride (PPMAH) were mixed through thermal process technique using heated two roll mill at 180°C with six different NBRr loadings rate. A few materials assessment was obtained such as tensile properties and Scanning Electron Microscopy (SEM) micrograph in order to prove the interaction of BSP fillers in PP/NBRr matrix. The results show that the incorporation of PPMAH has improved the tensile properties of the composites. The result from the SEM micrograph of the tensile fracture indicates that better adhesion was observed for all PPMAH compatibilized composites.
