    Effects of trans-polyoctylene rubber in polypropylene/recycled acrylonitrile butadiene/rice husk powder composites
    Composites of polypropylene/Acylonitrile butadiene rubber/Rice husk powder/ (PP/NBRr/RHP) with and without trans-polyoctylene rubber (TOR) were prepared, and the effects of trans-polyoctylene rubber were investigated. By using rice husk powder of 150300μm, five different compositions of PP/NBRr/RHP composites (i.e.100/0, 80/20, 70/30, 60/40 and 40/60 phr) were prepared in an internal mixer at 180 °C and 50 rpm rotor speed. The results indicate that the incorporation of TOR improved the tensile properties of PP/NBRr/RHPcomposites. Scanning electron microscopy of the fractured surfaces proved that TOR promoted good adhesion between the PP-NBRr matrices and RHP.

    In this study, the effect of epoxidized natural rubber-50 (ENR-50) as compatibilizer on polypropylene (PP)/ recycled acrylonitrile butadiene rubber (rNBR)/ banana skin powder (BSP) composite was analysed. The aim of this research is to study the effect of ENR-50 with manipulated rNBR loading. Tensile test showed by adding ENR-50, the tensile strength, Young’s Modulus and elongation at break of composite were increased by 9.034 - 2.09 %, 38.77 - 127.33 % and 24.98 - 59.99 % respectively.When rNBR loading were increased, the composite’s tensile strength decreases by average of 41.20 % and Young’s Modulus decreased by average of 59.29 % while elongation at break increased by average of 37.41 %. Scanning Electron Microscopy (SEM) morphology showed that composite with ENR-50 and low rNBR loading showed a better interfacial adhesion. From Fourier Transform Infrared Spectroscopy (FTIR) analysis, it was found that new bond was formed in the composite when ENR-50 were added. In the water absorption test, composite with ENR-50 and lower rNBR loading showed a less water absorption by 1 - 25 %. It can be concluded that ENR-50 can be used as compatibilizer in composite.
