摘要： The present disclosure provides for a coated flexible open-cell polyurethane foam structure. The coated flexible open-cell polyurethane foam structure includes a flexible open-cell polyurethane foam having a first major surface and a second major surface opposite the first major surface. The coated flexible open-cell polyurethane foam structure further includes a flexible heat conductive material covering 30 to 90 percent (cov., expressed in %) of a surface area of the first major surface of the flexible open-cell polyurethane foam in a predefined shape to provide one or more gaps exposing the flexible open-cell polyurethane foam between defined edges of the flexible heat conductive material, where each gap of the one or more gaps has a gap width according to Formula I: gap width (mm) ≤−0.196×cov. (%)+20.6 (Formula I) where a total surface area of the one or more gaps provides 70 to 10 percent of the surface area of the first major surface of the flexible open-cell polyurethane foam.

摘要： Polyurethane-polyisocyanurate foams are prepared using a polyether polyol made from an alkylene oxide mixture that contains a specified proportion of ethylene oxide. The selection of proper polyol equivalent weight and ethylene oxide content leads to the production of foams having a useful combination of properties.

摘要： Polyurethanes are made by curing a reaction mixture containing a polyether polyol that contains residues of a zinc hexacyanocobaltate catalyst complex. The reaction mixture contains certain chelating agents in small quantities. The amount of cobalt that is extractable from the polyurethane is reduced.

摘要： Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25 #C and having a glass transition temperature of at most 20 #C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

摘要： A polymer concrete composition has a base composition including a first isocyanate component and a first isocyanate reactive component, and one or more pre-coated aggregates that each has a base substrate and a two-component reaction product polymeric coating on an outer surface of the base substrate. The polymeric coating is the reaction product of a second isocyanate component and a second isocyanate-reactive component.
