Abstract: Disclosed herein is a method for producing polyurethane or polyisocyanurate foams. The method involves reacting a composition (Z1) with at least one polyisocyanate, and occurs in the presence of at least one nucleating agent and a blowing agent, in which the nucleating agent and the blowing agent are mixed to obtain a composition (Z2) that is added to the composition (Z1) before it is reacted with the at least one polyisocyanate. The composition (Z1) contains (i) 100 parts by mass of a composition (ZP) including at least one polyol and at least one catalyst that catalyzes formation of a urethane, urea or isocyanuarate bond, and (ii) from 0.05 to 10 parts by mass of a surfactant TD having an HLB value below 6 and no silicon atom.

Abstract: The present invention is directed to a process for preparing an inorganic aerogel, the process comprising the steps of providing a composition (I) suitable to form an inorganic gel with a gelation time tG, spraying the composition (I) into supercritical carbon dioxide at a spraying time tS to obtain gel particles, and drying the gel particles obtained in step (ii) by supercritical liquid extraction, wherein the ratio tS:tG is in the range of from 0.2 to 0.99. The present invention further is directed to the inorganic aerogel as such as well as the use of the inorganic aerogel according to the invention in particular for medical and pharmaceutical applications or for thermal insulation.

Abstract: The present invention relates to a process for the production of composite elements comprising a first and a second outer layer, a vacuum insulation panel between the two outer layers, rigid polyurethane foam in contact with the first outer layer and the underside of the vacuum insulation panel, and also rigid polyurethane foam in contact with the second outer layer and the upper side of the vacuum insulation panel, comprising application of a reaction mixture (R1) for the production of a rigid polyurethane foam onto the first outer layer, bringing the lower side of a vacuum insulation panel into contact with the unhardened reaction mixture (R1), application of a reaction mixture (R2) for the production of a rigid polyurethane foam to the upper side of the vacuum insulation panel, bringing the second outer layer into contact with the layer of the unhardened reaction mixture (R2), and finally hardening of the two rigid polyurethane foam systems (R1) and (R2) to give the composite element. The present invention further relates to composite elements thus obtainable, and also to the use of a composite element of the invention or of a composite element obtainable by a process of the invention, as component for refrigeration equipment or as construction material.
