  • Rigid foam from highly functionalized aromatic polyester polyols
    Publication number: 20040162359
    Abstract: The present invention provides rigid foams made from aromatic polyester polyols and polyisocyanates. The foams are isocyanate-based foams and are preferably prepared without cell nucleating agents, and are formed from a mixture containing an aromatic polyester polyol, a polyisocyanate, and a blowing agent that includes water. The foams have a high closed cell content with cells having diameters of about 160 microns or less, high thermal resistance, and flame retardancy.
