Abstract: 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 predict the thermal diffusivities of crosslinked closed cell polyethlyene foams and this model agrees well with the experimentally obtained results.
