Polymer blends (polypropylene) filled rice husk ash / Mohd Noorwadi Mat Lazim

This research concerned with the use of rice husk ash (RHA) as filler for polypropylene (PP) and its performance ability in PP matrix. Rice husk ash by weight (0, 5, 10 and 15%) and polypropylene were compounded in a twin screw extruder and injection moulding technique was applied in order to obtain testing specimen. It was found that tensile properties of PP/RHA blends were slightly increased upon increased filler loading meanwhile the MFI value is decreased as increased filler loading (5-15%). In addition, SEM micrograph revealed the homogeneity of RHA decreased as increased filler loading. More over, the FTIR spectroscopy, DSC and TGA technique were performed for characterization the filled specimen.
