    • 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.
    • 通过在泡沫制剂中包含特定的少量某些低分子量多元醇(通常具有100或更大的羟基数)来提供改进的可重复性聚酯聚氨酯泡沫。 这种多元醇的代表性有用物质包括脂族醇,例如甘油和赤藓糖醇,多羟基甲烷如三羟甲基丙烷,链烷醇胺如三乙醇胺和相对低分子量的烯化氧加合物如丙烯 - 甘油加合物等。 通过进一步使用直链醇或酚的某些烯化氧加合物,磺化石油,铵盐和含硅氧烷的共聚物作为共添加剂,提供了特别有效的可再加工泡沫配方。 如果需要,可以通过掺入稀释剂来改变添加剂和/或添加剂和共添加剂混合物的粘度和相容性。

    • 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. The second polyol is the reaction product of one or more alkylene oxides and, in the absence of polyol precursor compounds containing amine moieties, a compound selected from the group consisting of carbohydrates, a mixture of carbohydrates, and a mixture of one or more carbohydrates and one or more compounds selected from the group consisting of aliphatic diols, triols, water in an amount sufficient to form a diol upon reaction with alkylene oxide, and mixtures thereof.
