Blowing Agents for Polyurethane Foams pipes and a PhD from OsakaDescription Author: Dr. S. N. Singh, Huntsman Polyurethanes ISBN 978 1 85957 321 1 pages 104 Summary The polyurethane foam industry was radically shaken up by the discovery, in the mid 1980s, that certain chlorofluorocarbons (CFCs) used as blowing agents can damage the environment. Hydrochlorofluorocarbons (HCFCs) were developed as replacements, but they are now scheduled to be phased out as they also have ozone depleting potential. Global agreements
