ABSTRACT:
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.
