  • Liquid foam systems and ASTM E-84 class 1 rated rigid, high-density polyurethane foams and articles prepared therefrom
    Patent number: 8048935
    Abstract: An all-liquid foam-forming system contains: a first part (A) containing at least one liquid isocyanate or polyisocyanate; and a second part (B) containing: at least one liquid aromatic polyester polyol having an hydroxyl value of at least 110 mg KOH/gram and an average hydroxyl functionality of at least 2, at least two liquid halogenated flame retardants and water; the foam-forming system having an NCO/OH ratio of from about 0.9:1 to about 1.3:1; wherein the first and second parts are such that reaction therebetween forms a rigid polyurethane foam having a density of at least about 5 pcf and an ASTM E-84 Class 1 rating. Resultant polyurethane foams can be used to make articles, particularly for use in commercial decorative molding applications.
