Abstract: The present invention is directed to a process for preparing a porous material, at least comprising the steps of providing a gel comprising a solvent (S), wherein the solvent (S) has a volume (V1), pressurizing the gel with carbon dioxide at a temperature and a pressure at which carbon dioxide solubilizes in the solvent (S) forming gas-expanded liquid (EL), wherein the gas-expanded liquid (EL) has a volume (V2) and (V2) is greater than (V1); removing supernatant liquid, and drying the gel. The present invention further is directed to the porous material obtained or obtainable according to the process as such as the use of the porous material according to the invention in particular for medical, biomedical and pharmaceutical applications or for thermal insulation.

Abstract: A mold for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process carried out within the mold can have a lower part defining an interior volume for receiving the precursors of the porous material, wherein the interior volume defines the shape of the body to be manufactured, and at least a first opening through which the body is removable from the lower part. Surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material that is electrically dissipative and non-sticky to a gel formed from the precursors of the porous material and/or the body.

Abstract: The invention relates to a sandwich component composed of at least two building material plates which are arranged essentially parallel to one another at a distance from one another and have a polyurethane foam core between the spaced building material plates, wherein the ratio of the greatest measured compressive modulus of the polyurethane foam core in a direction oriented parallel to the building material plates to the compressive modulus of the polyurethane foam core in a direction oriented perpendicular to the building material plates is less than 1.7. To produce the sandwich components, a mixture of (a) at least one polyisocyanate component, (b) at least one component which comprises at least one polyfunctional compound which is reactive toward isocyanates and (c) at least one blowing agent is introduced by the high-pressure injection method into a hollow space between spaced building material plates. The process makes it possible to produce sandwich components whose foam core has reduced anisotropy combined with good insulation values.
