| titleOfInvention | polyol compositions providing improved flame retardance and aged k-factors to polyurethane foams |
| abstract | There is now provided a polyol composition containing a polyol having polyester linkages and a number average molecular weight of 400 or more, and at least about 8 php of a silicone-containing surfactant polymer. Either mixed into the polyol composition at the time of foaming, mixed into an isocyanate, or both, is an aliphatic or cycloaliphatic C4-C7 hydrocarbon. The polyol composition is used to make a polyisocyanate based closed cell rigid foam by reacting an organic isocyanate and the polyol composition in the presence of an aliphatic or cycloaliphatic C4-C7 hydrocarbon blowing agent. A method of making a polyisocyanate-based closed cell rigid foam using the inventive polyol is also disclosed. |
