Abstract: We measured the thermal conductivity of Kapton HN and Upilex R in the lengthwise direction of a single layer of material. The temperature range was investigated 0.1-9 K for Upilex and 0.2-5 K for Kapton. For both conductivities, we found a linear dependence on temperature that can be ascribed to the presence of crystalline units inside the solids.
