Abstract

An experimental procedure for the determination of temperature de pendence of thermal conductivity of foam insulations blown with condensable gases is presented. The procedure is used to investigate the effect of the blowing agent on thermal conductivity of a polyurethane system blown with CFC-11 or HCFC-123, at various stages of its aging A method to calculate the partial pressure of the blow ing agent in the cell gas mixture of the test specimens, from the data on thermal con ductivity, is also presented.
