Właściwości sztywnych pianek poliuretanowych w aspekcie stosowania nowych poroforów

A growing environmental concern has resulted among others in a gradual phase out of ozone depleting substances like chlorofluorocarbons and hydrochlorofluorocarbons. Influence of the different, alternative blowing agents on polyurethane foaming, cell structure, properties and ageing process of the rigid polyurethane foams was presented. On the base of literature study it was confirmed that pentanes can be long-term replacements for CFC-11 in rigid polyurethane foam manufacturing.
