| Abstract: | In this paper the factors affecting the initial K value and the aged K value of rigid PU foam and the relations between the factors are discussed. Practical technical methods for the improvement of the thermal insulating property of rigid PU foam are also appraised, which provides guiding principles for maintaining the thermal insulating property of rigid PU foam when CFC-11 replaced. |
