    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) at least comprising an isocyanate composition (A*) comprising a polymeric polyfunctional isocyanate as component (ai), a monomeric polyfunctional isocyanate as component (aii), at least one catalyst as component (ac),wherein composition (A) is substantially free of aromatic amines,and a solvent (B),reacting the components in the composition (A) obtaining an organic gel, and drying of the gel obtained in step b). 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.

    Abstract: The present invention relates to a dynamically evacuable, electrically operated apparatus comprising a contiguously evacuable region and a working region whose temperature can be controlled and which is thermally insulated by the contiguously evacuable region from the ambient temperature, and also a means for actively maintaining a vacuum so that the pressure in the contiguously evacuable region of the apparatus is constant over time within a prescribed pressure range, where the contiguously evacuable region makes up at least 20% by volume of the total volume occupied by a porous and/or cellular insulation material in the apparatus and the contiguously evacuable region comprises at least one organic aerogel and/or organic xerogel.

    Abstract: La presente invención se refiere a un proceso para la producción de materiales porosos, que comprende proporcionar una mezcla que comprende una composición (A) que comprende componentes adecuados para formar un gel orgánico y una mezcla de solventes (B), hacer reaccionar los componentes en la composición (A) en la presencia de la mezcla de solventes (b) para formar un gel y secar el gel, en el que la mezcla de solventes (B) es una mezcla de por lo menos dos solventes y la mezcla de solventes tiene un parámetro de solubilidad de Hansen dH en el intervalo de 3,0 a 5,0 MPa-1, determinado por el uso del parámetro dH de cada solvente de la mezcla de solventes (B). La invención se refiere además a los materiales porosos que se pueden obtener de esta manera y el uso de los materiales porosos como material de aislamiento térmico y en paneles de aislamiento de vacío.
