Patent number: 5690855Abstract: A polyol blend is disclosed for making cellular polyurethane foam products in the absence of halogenated hydrocarbon blowing agents. The products have good insulating performance, good compressive strength, and excellent dimensional stability. The blend comprises first and second polyols and is suitable for one-shot and two component reaction systems. The first polyol is the reaction product of one or more alkylene oxides and a compound selected from the group consisting of aliphatic diols, triols, pentaerythritol, water in an amount sufficient to form a diol upon reaction with alkylene oxide, and mixtures thereof.Type: GrantFiled: January 11, 1994Date of Patent: November 25, 1997Assignee: Sealed Air CorporationInventors: Charles B. Nichols, Michael R. Sandner, Richard R. Zielinski, II

Patent number: 4146498Abstract: Improved diecuttable polyester urethane foams are provided by the inclusion in the foam formulation of specified minor amounts of certain low molecular weight polyols, typically having hydroxyl numbers of 100 or greater. Representative useful species of such polyols include aliphatic alcohols, such as glycerol and erythritol, polymethylols such as trimethylolpropane, alkanolamines such as triethanolamine and relatively low molecular weight alkylene oxide adducts such as propylene-glycerol adducts and the like. Especially effective diecuttable foam formulations are provided by further employing, as co-additives, certain alkylene oxide adducts of linear alcohols or phenols, sulfonated petroleum oils, ammonium salts and silicone-containing copolymers. If desired, the viscosity and compatibility characteristics of the additive and/or additive and co-additive mixture may be modified by the incorporation of a diluent.Type: GrantFiled: February 15, 1978Date of Patent: March 27, 1979Assignee: Union Carbide CorporationInventors: Michael R. Sandner, Walter R. Rosemund, Ronald D. Carey
