Effects of Poly(vinylchloride)-Maleic Anhydride as Coupling Agent on Mechanical, Water Absorption, and Morphological Properties of Eggshell Powder Filled Recycled High Density Polyethylene/Ethylene Vinyl Acetate Composites

Abstract

The recycled high density polyethylene (rHDPE)/ethylene vinyl acetate (EVA)/ eggshell composites using poly(vinylchloride)-maleic anhydride (PVC-MA) as coupling agent was compounded using Brabender internal mixer.  The results showed that the compatibilization of rHDPE/EVA blends was enhanced by the addition of 6 phr of PVC-MA. Furthermore, the tensile, water absorption resistance, and interfacial adhesion properties were studied. Tensile properties such as tensile strength and Young’s modulus were improved, while the elongation at break was reduced by the addition of PVC-MA. The water absorption resistance was improved upon PVC-MA addition to the composites.
