Abstract: Described herein is a process for producing polyurethane foams having a density of 30 g/dm3 to 70 g/dm3, in which (a) aromatic polyisocyanate is mixed with (b) polymeric compounds having isocyanate-reactive groups, (c) optionally chain extender and/or crosslinking agent, (d) catalyst, (e) blowing agent including water, (f) 0.1% to 5% by weight of lactam, and (g) optionally additives, at an isocyanate index of 50 to 95 to form a reaction mixture, and the reaction mixture is converted to the polyurethane foam, wherein the catalyst includes metal catalyst and amine catalyst, and the amine catalyst has tertiary nitrogen atoms and the content of tertiary nitrogen atoms in the amine catalyst is from 0.0001 to 0.003 mol/100 g of foam. Also described herein is a polyurethane foam and a method of using such a flexible polyurethane foam for the production of cushions, seat cushions, or mattresses.

Abstract: The present invention relates to a process for converting moldings. Here, a molding comprising a foam and at least one fiber (F), wherein the fiber (F) is with a fiber region (FB2) located inside the molding is at least partially divided at least once, wherein at least one fiber (F) is completely divided. The invention further relates to the thus obtainable converted molding and to a panel comprising the converted molding and at least one layer (S1). The present invention further relates to a process for producing the panel and to the use of the converted molding/the panel according to the invention as a rotor blade in wind turbines for example.

Abstract: The present invention relates to a molding which comprises a foam and at least one fiber (F). The fiber (F) has a first part (FT1), a second part (FT2) and a third part (FT3). The third part (FT3) of the fiber (F) connects the first part (FT1) and the second part (FT2) of the fiber (F) and is arranged on a second side of the foam. A first region (FB11) of the first part (FT1) of the fiber (F) and a first region (FB12) of the second part (FT2) of the fiber (F) are located inside the molding and are not in contact. A second region (FB21) of the first part (FT1) of the fiber (F) and a second region (FB22) of the second part (FT2) of the fiber (F) project from a first side of the foam. The present invention further relates to a process for producing the moldings according to the invention and to a panel which comprises the molding according to the invention and at least one layer (S1) and also to a process for producing the panel.

Abstract: The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.

Abstract: The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.

Abstract: The invention relates to a molding composed of extruded foam, wherein at least one fiber (F) is present with a fiber region (FB2) within the molding and is surrounded by the extruded foam, while a fiber region (FB1) of the fiber (F) projects from a first side of the molding and a fiber region (FB3) of the fiber (F) projects from a second side of the molding, and the extruded foam is produced by an extrusion process comprising the following steps: I) providing a polymer melt in an extruder, II) introducing at least one blowing agent into the polymer melt provided in step I) to obtain a foamable polymer melt, III) extruding the foamable polymer melt obtained in step II) from the extruder through at least one die aperture into an area at lower pressure, with expansion of the foamable polymer melt to obtain an expanded foam, and IV) calibrating the expanded foam from step III) by conducting the expanded foam through a shaping tool to obtain the extruded foam.

Abstract: The present invention relates to a molding made from foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fibers (F) that are not surrounded by the foam thus each project from one side of the corresponding molding. The foam comprises at least two mutually bonded foam segments.
