Thermal Stability Of

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.

Thermal degradation of the composite constituted by high density polyethylene (HDPE) and microencapsulated red phosphorus (MRP) were studied using thermogravimetric (TG) data obtained at different heating rates. The kinetic models and parameters of the thermal degradation of MRP/HDPE composite were evaluated by FWO, KAS and IKP method. It indicates that the activation energy E of 4 % MRP/HDPE composite is higher than HDPE for three methods. MRP could improve the thermal stability and slow down the thermal degradation of HDPE. With adding MRP, the degradation mechanism of HDPE is changed and the degradation rate decreases.

Thermal Stability Of

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.
