Using the transient plane source (TPS) method, the thermal conductivities of a series of crosslinked closed-cell polyethylene foams were measured. The experimental values obtained were compared to measurements made by a steady-state method (heat-flow meter). Through the use of the TPS technique, it was possible to observe how physical characteristics such as cell size, density and carbon black content affected the overall thermal conductivity. The authors found that the trends ...
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 ...
