| titleOfInvention | Preparation of urethane and isocyanurate foams in the presence of a low boiling point blowing agents |
| abstract | This invention relates to a process for prenparing a rigid, closed-celled polyisocyanate-based foam nin the presence of water and a blowing agent. The nblowing agent comprises one or more organic compounds, nparticularly halocarbons, having a boiling point of from n222K to 272K at atmospheric pressure, and is nsubstantially free of organic compounds having a boiling npoint of 273K or greater. Preferred halocarbons are nchlorofluoroethanes, especially chlorodifluoroethane n(R-142b) and fluoroethanes. |
