Abstract:

Disclosed are polyurethane foam-forming compositions with a phase stable isocyanate-reactive composition that includes a halogenated olefin blowing agent that has low or no ozone depletion potential and low global warming potential. Such polyurethane foam-forming compositions are suitable for spray application to produce polyurethane foams that are believed to exhibit good fire resistance properties, low smoke generation and low or no scorch due to reduced exotherm, thereby making them particularly suitable for use, for example, as relatively thick wall and/or roof insulation.
