Beschreibung
Zusammenfassung:	Formulated polyol compositions include a non-halogenated polyol, a halogenated polyol, a phosphorus-containing flame retardant, an HFO and/or HCFO blowing agent and certain urethane catalysts. The compositions exhibit excellent storage stability. Foams made from the formulated polyol compositions have unexpectedly improved fire performance, as indicated by certain fire tests.
