Thermal Conductivity of Teflon, KEL-F, and Duroid 5600 at Elevated Temperatures

Abstract

The thermal conductivity values of the fluorocarbon plastics, Teflon, Kel-F, and Duroid 5600, were determined at mean specimen temperatures ranging from approximately 185 deg F to their respective gel-points. Measurements were obtained utilizing a comparative method technique based on unidirectional steady-state heat-flow theory. For the range of temperatures within which the materials were investigated, it was found that Teflon consistently exhibited higher values than Kel-F and lower values than Duroid 5600. At 350 deg F, the thermal conductivities obtained were: Teflon - 2.37 BTU/hr/ft2/degF/in, Kel-F - 1.72 BTU/hr/ft2/degF/in, Duroid 5600 - 3.58 BTU/hr/ft2/degF/in. The thermal conductivities were found to increase with increasing temperatures.
