A halogen-free blowing agent is used to produce isocyanate-based polymeric foams. The blowing agent is an organic liquid which is free from halogens and contains a positive binary azeotrope having a minimum boiling temperature in the range of about 15.degree. C. to about 80.degree. C. at normal atmo ...

Ashida Kaneyoshi: Halogen-free blowing agents that include cycloaliphatic hydrocarbons and are suitable for isocyanate-based polymeric foams.. Nisshin Spinning, June 14, 1995: EP0657495-A1 (10 worldwide citation)

The mfr. uses a halogen-free organic liq. as a physical blowing agent for the foam. The organic liq. contains a positive azeotrope of min. b.pt. 15-80 deg.C at normal atmospheric pressure and comprises (a) a 5-7C cycloaliphatic hydrocarbon, and (b) a 4C aliphatic ether, a 2-5C aliphatic carboxylic a ...
