摘要： The present invention provides all liquid, two-component foam forming compositions for forming fire-resistant rigid polyurethane foams comprising a chlorine-free liquid flame retardant (FR) additive. The compositions comprise a polyisocyanate component and, as a separate component, a polyol component of a blend of one or more high hydroxyl functional aromatic polyester polyols and one or more low hydroxyl functional aromatic polyester polyols, a novolac polyether polyol, a trimerization catalysts, a liquid FR additive, preferably, one FR additive, more preferably, a halogen free FR additive, and water, or water and a physical blowing agent as a blowing agent. The low hydroxyl functional aromatic polyester polyols enable the provision of readily processible, all liquid polyol components having a low viscosity as well as ASTM E84A Class A rated rigid polyurethane foams.
