Effect of Maleic Anhydride (MA) on Properties of Recycled High Density Polyethylene/Ethylene Vinyl Acetate/Egg Shell Powder (rHDPE/EVA/ESP) Composites

The difference in polarity of recycled high density polyethylene (rHDPE) and ethylene vinyl acetate (EVA) blends leads to poor mechanical properties (Atul Rajan, 2013). Present works aim at finding the effects of maleic anhydride on the mechanical, morphological, and water resistance properties of rHDPE/EVA/ESP blends. It is shown that there is a significant improvement on tensile strength, interfacial adhesion between components, and water absorption resistance of adding maleic anhydride (MA) to rHDPE/EVA/ESP blends. This study may suggest that the MA can act as compatibilizer to enhance the interfacial interaction between the rHDPE and EVA matrix in the rHDPE/EVA/ESP composites.
