Abstract
A method to make a silicone foam. A layer of crystalline material is embedded in a layer of uncured silicone. The crystalline material is closely packed in crystal-to-crystal contact, the crystals being provided in a plurality of sizes or ranges of size to increase the packing ratio of the crystals as a group. The silicone is cured and then the crystals are dissolved out with a solvent that dissolves them but does not dissolve the silicone.
