Identification of CFC and HCFC Substitutes for Blowing Polyurethane FoamInsulation Products

摘要

The paper gives results of a systematic search to identify additional candidatesas third-generation blowing agents, chemical compounds that are not stratospheric ozone depleters that can be used as substitutes for chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) blowing agents in rigid polyurethane foam insulating materials. To identify the most promising substitutes, potential third-generation blowing agents were ranked using a methodology developed for this project.
