Abstract
The present invention discloses a phase stable polyol blend composition containing a sucrose and dipropylene glycol co-initiated propylene oxide polyether polyol, a polyester polyol, a compatibilizing agent and a hydrocarbon blowing agent. The polyester polyol is preferably a phthalic anhydride-initiated polyester polyol. The compatibilizing agent is a butanol-initiated propylene oxide polyether surfactant.
