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.

The effect of salicylic acid as a coupling agent on the tensile properties, and morphology analysis 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 but lower elongation at break than rHDPE/WF composites. The SEM micrographs showed that the wood fiber was more widely dispersed in the rHDPE matrix with addition of ethyl salicylate than rHDPE/WFM.

The effect of phthalic anhydride (PAH) as a coupling agent on the tensile properties, swelling behavior, and x-ray diffraction of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. rHDPE/WF and rHDPE/WFPAH composites were prepared using Brabender plasticorder at temperature of 160°C with rotor speed of 50 rpm. The results indicate that rHDPE/WFPAH composites showed higher tensile strength and percentages of equilibrium water absorption, but lower interparticle spacing (d) compared to rHDPE/WF composites.

Wollastonite is one type of inorganic filler. The effects of wollastonite loading on tensile properties of wollastonite (WS) filled high density polyethylene (HDPE)/Natural Rubber (NR) composites was studied. The HDPE/NR/WS composites were prepared by using Brabender EC Plus at a temperature of 180 °C with rotor speed of 50 rpm for 10 min. It was found that the increasing of wollastonite loading had decreased the tensile strength and elongation at break, whereas the Young’s modulus of the HDPE/NR/WS composites had increased with the increasing of wollastonite loading.

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 maleic anhydride as a coupling agent on the tensile properties and morphology of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. rHDPE/WF composites with different wood fiber loading and the addition of maleic anhydride were prepared with Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WFM composites with maleic anhydride exhibit higher tensile strength and modulus of elasticity than rHDPE/WF composites. rHDPE/WFM with maleic anhydride composites gave a better interfacial adhesion between the matrix and the fiber than rHDPE/WF composites as evidence using Scanning electron microscopy (SEM).

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.

Abstract This study investigates the properties of high-density polyethylene (HDPE) with different soya spent powder (SSP) blend contents upon oven aging. The aged properties of the HDPE/SSP blends were studied by using tensile test, thermogravimetric analysis, differential scanning calorimetry and Fourier transform infrared analysis. The tensile strength and elongation at break (Eb) decreased inversely proportional to SSP content and aging period. The thermal stability of the blends was significantly reduced after 21 days of aging. After aging, the melting temperature and crystallinity of the blends decreased with increasing aging period. These results revealed that samples with higher SSP content are more brittle upon oven aging.

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.
