A very thin filled silicone foam layer is formed from a composition that includes a curable polysiloxane composition including an alkenyl-substituted polyorganosiloxane, a hydride-substituted polyorganosiloxane, and a cure catalyst; a plurality of expanded polymer microspheres having a largest dimension of less than the thickness of the foam; and a filler composition, wherein each component of the filler composition has a largest dimension of less than the thickness of the foam, the filler composition comprising a particulate ceramic filler, a particulate calcium carbonate filler, or a particulate aluminosilicate clay filler having a plate morphology, or a particulate aluminosilicate clay filler having a hollow tubular morphology, a particulate polymeric silsesquioxane filler, or a particulate methyl-phenyl MQ filler, or a plurality of glass microspheres, or a particulate paraffin wax, or a combination thereof; wherein the curable filled composition has a viscosity of less than 400,000 centiStokes, or 100,000 to 350,000 centiStokes.

Filled silicone foam layer, compositions and methods for their manufacture, and articles including the filled silicone foam layer

A composite thermal management sheet for a battery includes a silicone foam layer; and a reactive filler composition disposed within the silicone foam layer, the reactive filler composition including a first filler that decomposes to generate water upon initial exposure to heat; and a second filler different from the first filler, wherein the second filler forms a thermal barrier layer with a decomposition product of the first filler, or absorbs the water, or both.
