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)&#x2264;&#x2212;0.196&#xd7;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.

A composition for forming a foamed silicone elastomer is disclosed. The composition comprises: A) an organopolysiloxane having at least two silicon-bonded ethylenically unsaturated groups per molecule; B) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; C) a hydrosilylation catalyst; D) a chemical blowing agent; and E) a physical blowing agent. The hydrosilylation catalyst C) is present in a catalytically effective amount. The chemical blowing agent D) has at least one hydroxyl (OH) group, and is present in an amount to provide a OH content &#x3e;0 and &#x3c;500 parts per million (ppm). The physical blowing agent E) undergoes a phase change from a liquid to a gaseous state during exposure to atmospheric pressure and a temperature &#x2265;0&#xb0; C. The blowing agents D) and E) are different from one another. A foamed silicone elastomer, and methods of forming the composition and foamed silicone elastomer are also disclosed.
