ACCELERATION EFFECTS OF SPECIMEN THICKNESS AND STORAGE TEMPERATURE ON THERMAL CONDUCTIVITY CHANGE OF PLASTIC INSULATION FOAMS

This paper describes the measured results of thermal conductivity change of plastic insulation foams. The partial gas pressure of blowing agent and thermal conductivity within foam are measured where the foam is sliced to thin specimens, and the storage temperature is increased to promote thermal conductivity change. The measured data were compared the simulated results of the partial pressure of blowing agent and thermal conductivity based on the analytical solution.
