Effects of a titanate coupling agent on the mechanical and thermo-physical properties of talc-reinforced polyethylene compounds

The effect of a titanate coupling agent on the thermal conductivity of talc filled high density polyethylene. Moisture content and mechanical properties were studied in addition to thermal conductivity. Samples with and without the isopropyl tri(dioctyl)phosphate titanate were investigated. Thermal conductivity did not change with the addition of the coupling agent, however the stiffness and tensile strength of the samples did increase....

Measurement of the thermal diffusivity and specific heat capacity of polyethylene foams using the transient plane source technique

The authors obtained a collection of crosslinked closed cell polyethlyene foams from a commercial supplier and then characterized the thermal properties of these foams. The characterization involved the use of the TPS technique to measure thermal conductivity, thermal diffusivity and specific heat capacity. It was found that increasing density resulted in a decreased thermal diffusivity and an increased specific heat capacity per unit volume. A theoretical model was developed to ...

Synergistic effect of iron and intumescent flame retardant on shape-stabilized phase change material

In this article, the transient plane source technique was used to determine the effect of iron, a flame retardant shape-stabilized phase change material (FSPCM), on the thermal conductivity of a sample of paraffin/high-density polyethylene (HDPE). With the results, it was determined that iron could be dispersed within the HDPE and paraffin samples, so as to improve the flame retardant efficiency. The results also concluded that the thermal conductivity of ...

Effect of expanded graphite on properties of high-density polyethylene/paraffin composite with intumescent flame retardant as a shape-stabilized phase change material

This research proposed a new, flame retardant, shape-stabilized phase change material (PCM), for use in thermal energy storage. Typical paraffin and high-density polyethylene has great shape retention, however is highly flammable and has a low thermal conductivity. Researchers introduced expanded graphite and an intumescent flame retardant to the mix to improve the thermal properties and flammability, respectively. After several tests, including a thermal conductivity evaluation, on multiple variations of the ...
