Effect of calcium carbonate onmechanical and thermal properties of kenaf recycle polypropylene/polyethylene wood plastic composites

Wood recycle plastic composite (WrPC) was prepared using kenaf wood flour, recycle polypropylene (rPP), recycle polyethylene (rPE) and maleic anhydried polypropylene (MAPP) in the presence of calcium carbonate (CaCO3) filler. Kenaf wood flour, rPP, rPE, MAPP were premixed manually and fed into singl...
