Abstract: The present invention relates to a method for manufacturing a composite element comprising a single- or multi-part core and an envelope which are in a force fit combination with each other, at least comprising providing a single- or multi-part core of an evacuable organic material; at least partly enveloping the core with an envelope to obtain a composite element precursor; and treating the composite element precursor for a period leading to an at least partial softening of the evacuable organic material and of the envelope surface apposing the core. The present invention further relates to composite elements obtained or obtainable by a method of the present invention and also to the method of using a composite element of the present invention as a vacuum insulation panel or as a thermal insulation material.

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.
