    摘要： A polyisocyanate component, a polyurethane foaming system, and an article made therefrom, wherein the polyisocyanate component includes (a) a preformed mixture including an aromatic oxazolidone compound that is the reaction product of at least one aromatic epoxide and at least one first polyisocyanate having an average isocyanate functionality of no more than 2.7 and greater than 1.8, in the presence of at least one catalyst, the aromatic oxazolidone compound includes at least one free isocyanate group and at least one aromatic oxazolidone group, the aromatic oxazolidone group includes an aromatic group and an oxazolidone group, and (b) at least one second polyisocyanate has an average isocyanate functionality equal to or greater than 2.7 and less than 6.0. The second polyisocyanate is added to the preformed mixture to form the polyisocyanate component. The polyisocyanate component has a viscosity of no more than 4.0 Pa-sat 25° C., an aromatic oxazolidone group content of 2 weight percent to 10 weight percent based on a total weight of the polyisocyanate component, and an average isocyanate functionality of from 1.8 to 6.0.

    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.
