Non-isothermal Crystallization Behavior of Rice Husk Powder/HDPE Composites

Application of wood plastic composites (WPC) has been increased in recent years because of their good processability, mechanical properties and environmental-friendly features. We prepared the rice husk powder/ high-density polyethylene (HDPE) by extrusion-molding. Using Differential Scanning Calorimeter (DSC), we analyzed the non-isothermal crystallization behavior of the composites. With cooling rate increasing in the DSC experiments, crystallization time decreased, whilst crystallization enthalpy and relative crystallinity increased. The results show that rice husk powder exhibits the role of heterogeneous nucleation in the composites. Rice husk powder promots crystallization behavior of the composites. The DSC data show a better linear relationship that is analyzed successfully by the Mo Zhishen method. The rice husk powder increases the crystallization rate of composites at the same crystallinity.
