The present invention relates to a molding made of expanded bead foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the expanded bead foam. The two ends of the respective fibers (F) that are not surrounded by the expanded bead foam thus each project from one side of the corresponding molding. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings of the invention from expanded bead foam or the panels of the invention and for the use thereof, for example as rotor blade in wind turbines.

The present invention relates to foam. In particular, the present invention relates to profiled foams and processes for profiling absorbent foam products. More particularly, the present invention relates to processes for producing a profiled absorbent polyurethane foam product, comprising the steps of foaming, curing, profiling and drying, wherein profiling occurs before drying; and absorbent aliphatic polyurethane foam products having at least one profiled surface.

The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.

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.

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.

The technology described in this document can be embodied in an acoustic enclosure for a speaker system disposed in a portion of a vehicle seat. The acoustic enclosure includes a rigid plate configured to be attached to a frame, a first section, and a second section. The rigid plate configured to support a speaker disposed in part within the acoustic enclosure. The first section is constructed from expanded resin, and disposed in contact with the rigid plate. The second section is disposed in contact with the first section, between the second section and the rigid plate. The first and second section together define a housing of the acoustic enclosure that includes at least one cavity configured to accommodate a portion of the speaker.

Foam slabs and methods and apparatus, including foaming dies, for making and using foam slabs.

A portable structure or hunting blind includes a floor railing or frame system for supporting side walls and a roof. The side walls and roof are formed of polyurethane foam. The side walls and roof can be manufactured by applying uncured polyurethane foam over a sheeting material, which is supported by a removable set of forms. The polyurethane foam is then allowed to cure, and once cured the forms are removed. A door and windows and floor decking can then be installed to finish out the hunting blind. The exterior of the polyurethane foam walls and roof can be coated with an elastomer coating for UV protection.

The present invention relates to a method for manufacturing a laminated object. A foam core and a skin are provided and the foam core and the skin are arranged relative to each other. The skin is heated. The skin is pierced by a vacuum application device. Further, vacuum is applied via the vacuum application device so as to withdraw a gaseous medium, in particular air, from within the foam core and from a space or spaces between the foam core and the skin, in order to draw the skin towards the foam core. Furthermore, the invention provides a manufacturing device for manufacturing a laminated object, laminated objects comprising a foam core and a skin, a method for producing pallets comprising a foam core and a skin, as well as pallets comprising a foam core and a skin.

A method for producing a foamed thermally crosslinked mass system, wherein the mass system is foamed at a first temperature in a first step, and crosslinker substances are added to the mass system in a subsequent step at a second temperature lower than the first temperature, wherein the crosslinker substances are crosslinker substances for thermal crosslinking of the mass system.
