Mechanical and thermo-physical properties of high-density polyethylene modified with talc

High-density polyethylene-talc-carbon black composites were prepared with varying amounts of talc to determine its effect on the thermo-physical properties of the composites. Carbon black was added in a content of 3.5 wt. % because it was previously determined that the mechanical properties of the composites were depreciated at higher loadings. It was found that the addition of talc enhanced the mechanical properties, as well as the thermal conductivity, and thermal diffusivity. The ...

Understanding in crystallization of polyethylene: the role of boron nitride (BN) particles

The authors examine the melting and crystallization behavior of a polyethylene/boron nitride composite to understand an unexpected exothermic peak when the BN content was greater than 10 wt. %. Based on these observations, an optimal annealing temperature of the composite was investigated to enhance its thermal conductivity. The appearance of the peak was determined to depend on the different nucleated capability of the different BN aggregates in local area. An annealing ...

Thermally conductive phase-change materials for energy storage based on low-density polyethylene, soft Fischer-Tropsch wax and graphite 

Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. In this study, conductive fillers were added to wax- and polyethylene-based PCMs to improve their thermal conductivity. A Thermal Constants Analyser measured the thermal conductivity of the PCMs using the transient plane source (TPS) method. Results indicated that both nanoparticles improved thermal conductivity, but a lower concentration of expanded graphite improved conductivity more than normal ...

Study on insulating thermal conductive BN/HDPE composites

In this article, researchers set out to determine the thermal characteristics of boron nitride reinforced high-density polyethylene composites. Various filler contents were studied through thermal characterization and it was determined that the composites containing 30% filler elicited the best thermal insulation and mechanical properties. The results displayed that the lower the filler content, the higher the thermal conductivity of the reinforced composite. Researchers also concluded that the smaller the boron nitride ...
