Abstract
This invention relates to rigid polyurethane foams which are co-blown with a mixture of a hydrocarbon blowing agent and a halogenated olefin blowing agent. This invention also relates to a process for preparing these rigid polyurethane foams, and to an isocyanate-reactive component containing a polyol blend and the mixture of blowing agents. Phase stable isocyanate-reactive blends are also described.
