Abstract
This report presents a joint project of the Society of the Plastics Industry and the Institute for Research in Construction of the National Research Council of Canada. The objectives of this project were to manufacture two spray polyurethane foams bases on the existing industrial technology but using alternative blowing agents, compare the properties of these foams with those blown with CFC-11 and establish a basis for development of new polyurethane spray foams with alternative blowing agents. The following properties were examined: thermal resistance, dimensional stability, compressive strength, water vapour permeance, blowing agent concentration and effective diffusion characteristics. This study combined advanced industrial and academic research, predicted 25-year thermal performance from 3-4 months testing results and characterized foams with selected thermal, moisture and mechanical properties.
