Abstract: The authors used a variety of techniques to determine the thermal properties of polymethyl methacrylate (PMMA), including thermal conductivity, thermal diffusivity, specific heat and density. The measurements are performed in the temperature range from -70°C to 80°C. The results from the different techniques used to characterize the PMMA (GHP, GHF, TPS, THS) are all compared to see whether they agree with one another.
