The report gives results of a cooperative effort to identify chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) substitutes for blowing polyurethane foam insulation products. More than 100 chemicals have been identified and ranked as polyurethane foam blowing agent candidates. The systematic investigation involved the analysis of vapor thermal conductivity predictive models and utilizing this methodology to identify and screen potential new foam blowing agents. Collection of physical/chemical properties of the new candidates enabled an overall evaluation. Based on the vapor thermal conductivity, boiling point, and other important properties, the chemical compounds were ranked to identify the most promising new blowing agent candidates. To efficiently evaluate new foam blowing agents, the compounds were placed and evaluated in 14 groups based on chemical structure.
