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 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.

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.

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.

Nanocomposites with high density polyethylene (HDPE)/nanoclay/bamboo flour were fabricated by melt compounding. Their thermal behaviors and degradation kinetics of the composites with different clay contents were characterized through dynamic and isothermal Thermogravimetric (TG) analysis. It was found that the use of nanoclay improved the thermal stability of the composites. The nanolayers could act as a barrier for the degradation of HDPE/bamboo hybrids. The addition of compatibilizer also improved the thermal stability of HDPE/bamboo composites, but the effect was less significant than clay. It seems that there is no much difference in the thermal behaviors between HDPE/nanoclay/bamboo systems with and without the addition of compatibilizer. The activation energy values varied very little for different clay contents in the composites. Thermal decomposition process of HDPE/bamboo composites with various clay additions had similar TG curves.

In this study,silvergrass (SV) reinforced high density polyethylene (HDPE) composites (WPCs) were prepared by injection molding. The effects of maleated polyethylene (MAPE), Slivergrass fibers (SV) content on the thermal, crystalline properties of WPCs were investigated. It was found that compared with the untreated WPCs, the thermal stability of the composites after incorporation of MAPE was significantly improved. Moreover, the results show that with MAPE adding, SV was an effective heterogeneous nucleating agent.
