Abstract: The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a composition (A) comprising components suitable to form an organic gel and a solvent (B), reacting the components in the composition (A) in the presence of the solvent (B) to form a gel, and drying of the gel obtained in step b), wherein the composition (A) comprises at least one compound (af) comprising phosphorous and at least one functional group which is reactive towards isocyanates. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels, in particular in interior or exterior thermal insulation systems as well as in water tank or ice maker insulation systems.

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 present invention relates to a process for preparing a porous material, at least providing a mixture (I) comprising a composition (A) comprising components suitable to form an organic gel and a solvent(B), reacting the components in the composition (A) in the presence of the solvent (B) to form a gel, and drying of the gel obtained in step b), wherein the composition (A) comprises a catalyst (C) selected from the group consisting of alkali metal and earth alkali metal salts of a saturated or unsaturated monocarboxylic acid with 4 to 8 carbon atoms. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels, in particular in interior or exterior thermal insulation systems.

Abstract: A method for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process, including (i) providing a mold, containing a lower part defining an interior volume for receiving the precursors of the porous material, wherein the lower part comprises a first opening, and surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material being electrically dissipative and non-sticky to the precursors of the porous material and/or the body, (ii) filling precursors of the porous material into the lower part in a first inert or ventilated region, wherein the precursors include two reactive components and a solvent, (iii) removing the body from the lower part through the first opening after a predetermined time, (iv) disposing the body onto a support, and (v) removing the solvent from the body.
