Recycled high density polyethylene/ethylene vinyl acetate/taro powder composites: the effect of polyethylene-grafted-maleic anhydride on tensile properties and thermal stability

Taro powder (tp) filled composites based on recycled high density polyethylene (rhdpe)/ ethylene vinyl acetate (eva) were prepared via melt blending method. polyethylene-grafted-maleic anhydride (pe-g-mah) was used as a compatibilizer to enhance interfacial bonding of rhdpe/eva/tp composites. the effects of tp loading and the addition of pe-g-mah on the tensile properties and thermal stability of rhdpe/eva/tp composites were investigated and studied. findings indicated that increased tp loading will reduce tensile strength and elongation at break while increasing the modulus of elasticity. the thermal stability of rhdpe/eva/tp composites improved by increasing filler loading. with respect to both tensile properties and thermal stability,rhdpe/eva/tp composites with pe-g-mah performed better than the composites without the addition of compatibilizers. © 2015 penerbit utm press. all rights reserved.
