Abstract: 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 observed when using the heat-flow meter were also seen when using the TPS technique, but the TPS technique resulted in thermal conductivity values about 20% higher than the heat-flow meter. This disagreement is talked about in the article.
