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.

The effect of polyethylene grafted maleic anhydride as a compatibilizer on the tensile properties, and swelling behavior of recycled high density polyethylene/ethylene vinyl acetate/ waste tyre dust (r-HDPE/EVA/WTD) composites was studied. r-HDPE/EVA/WTD composites with different tyre dust loading and the addition of polyethylene grafted maleic anhydride (PEgMAH) were prepared with Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that r-HDPE/EVA/WTD/PEgMAH composites exhibit higher tensile strength, modulus of elasticity, and mass swell resistance than r-HDPE/EVA/WTD composites.

Palm kernel shells (PKS) filled recycled high density polyethylene (rHDPE) biocomposites were produced using melt mixing. The biocomposites were prepared on Brabender Plasticorder at temperature of 185 °C and rotor speed of 50 rpm by varying filler loading (0 to 40 phr). In this study, the effect of PKS loading on rheological properties and thermal stability of rHDPE/PKS were investigated. Rheological study of the biocomposites was carried out by means of capillary rheometer under temperature of 190 °C, 200 °C and 210 °C. Thermal properties of biocomposites were studied by using thermo gravimetric analysis (TGA). The rheological results showed that the flowability of the composite increased with increasing temperature. Meanwhile, the result of TGA showed that at higher PKS loading, rHDPE/PKS biocomposites had lower total weight loss. The thermal stability of the biocomposites was reduced due to the addition of filler loading.

The EVA/NR/PF composites with and without IAMA were prepared using Brabender Plasticoder at 160oC with 50rpm rotor speed. The effects of potash feldspar loading and isophathalic acid-maleic anhydride (IAMA) on the tensile properties and morphology analysis of EVA/NR/PF composites were studied. The results indicated that tensile strength for EVA/NR/PF and EVA/NR/PFIAMA composites decreased but M100 increased as the filler loading increased. EVA/NR/PFIAMA composites showed higher value of tensile strength and M100.

The effect of phthalic anhydride as a coupling agent on the tensile properties and thermal stability of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied.  Both composites rHDPE/WF and rHDPE/WF/PAH (modified with phthalic anhydride) were prepared using Brabender Plasticorder at a temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WF/PAH composites exhibit higher tensile strength and modulus of elasticity than rHDPE/WF composites. It was also found that the addition of phthalic anhydride offers better thermal stability in rHDPE/WF/PAH composites than that of rHDPE/WF composites.

This paper describes tensile properties, and morphology analysis of different composition of RHDPE and EVA blends were studied. The main goals are to describe the effect of Caprolactam as compatibilizer used to improve the compatibility between RHDPE and EVA. The RHDPE/EVA blends were prepared at 160°C and the rotor speed of 50rpm in an internal mixer. The tensile strength for RHDPE/EVA blends increased, while adding Caprolactam by 6phr in the blend formulation significantly improved the tensile properties. The SEM micrograph show a better interfacial adhesion between RHDPE and EVA phases for RHDEP/EVA/Caprolactam blends than RHDPE/EVA blends.

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.

The effect of salicylic acid/ethanol as a coupling agent on the tensile properties and thermal stability of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. Both composites rHDPE/WF and rHDPE/WFM (treatment with salicylic acid) were prepared using Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WFM composites with salicylic acid exhibit higher tensile strength and modulus of elasticity and lower elongation at break than rHDPE/WF composites. It was also found that the addition of salicylic acid/ethanol shows better thermal stability in rHDPE/WFM composites than rHDPE/WF composites.

The compatibilized poly ethylene vinyl acetate copolymer (EVA)/high density polyethylene (HDPE) /organomodified montmorillonite (OMMT) blend nanocomposites were prepared in a co-rotating twin-screw extruder followed by injection molding. Montmorillonite clay was modified by octadecylamine and aminopropyltriethoxysilane to make it organophilic. Maleic anhydride grafted high-density polyethylene was used as a Compatibilizer. Nanoclay was added in different proportions to the selected EVA/HDPE blend composition. The concentration of nanoclay was varied from1 to 5 phr in the polymer blend. The resulting nanocomposites were evaluated in terms of their water absorption behavior. Moisture absorption behavior of compatibilized blends is lower than their corresponding blend. On adding the nanoclay the moisture absorption behavior of blend nanocomposites changed at 4 phr nanoclay loading.
