Johnson, Jr, R T

The temperature dependence of the electrical conductivity of three rigid polyurethane foams prepared using different formulations has been measured to approx. 320/sup 0/C. The materials exhibit similar conductivity characteristics, showing a pronounced increase in conductivity with increasing temperature. The insulating characteristics to approx. 200/sup 0/C are better than that for phenolic materials (glass fabric reinforced), and are similar to those for silicone materials (glass microsphere reinforced). At higher temperatures (500 to 600/sup 0/C), the phenolics and silicones are better insulators.
