A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m.sup.2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.

A real wood sheet capable of being used for automatic wrapping, the real wood sheet including a wood layer; a mesh layer disposed on a surface of the wood layer; and a flexible layer disposed on a surface of the mesh layer such that the mesh layer is disposed between the wood layer and the flexible layer.

A membrane device for manufacturing a crash pad for a vehicle including a real wood sheet includes a vacuum device main body having a plurality of vacuum holes such that a real wood sheet to be temporarily attached to a core is mounted in the vacuum device main body, a cover having a silicone film to define a vacuum space together with the vacuum device main body, a vacuum module to suck air in the vacuum device main body through the vacuum holes, and a control unit to compress the real wood sheet and the core, which are temporarily attached and mounted on the vacuum device main body, for a preset time by sucking air in the vacuum space through the vacuum holes in a state in which the vacuum device main body is covered by the cover.

A flexible sound barrier and rigid mounting assembly, and a method of attaching to a vehicle. The sound barrier assembly includes a rigid substrate, and flexible noise barrier and decoupling layers. The decoupling and noise barrier layers are bonded, and an adhesive bonds the decoupling layer to the substrate. The decoupling and noise barrier layers are fixedly held in place by the substrate. The substrate can include slots that fit over mounting studs on the vehicle wall. The noise barrier and decoupling layers can include mounting holes that extend through both layers, where the mounting holes line up with the slots, and fit over the mounting studs. The assembly can be mounted on the mounting studs and stud fasteners can fit through a mounting hole without compressing the noise barrier and decoupling layers and sandwich the rigid substrate surrounding a slot between the stud fastener and the vehicle wall.

A floor element includes a substrate made of polymer, a top layer on one of the two sides of the substrate and a polymeric foamed layer on the other of the two sides of the substrate. The density of the polymeric foamed layer is less than 120 kg/m.sup.3.

The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a KEE cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam layer composition layer with at least one cap layer composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A method for producing a sandwich panel with a reinforced foam core includes inserting rod-shaped, thermoplastic reinforcing elements into a thermoplastic foam material such that the reinforcing elements extend through the foam material. End regions of the reinforcing elements project out of the foam material. The foam material is thermoformed to form a reinforced foam core, wherein the end regions of the reinforcing elements are integrally formed by applying temperature and pressure to the cover surfaces of the foam material and are bonded to the foam material in a fused connection. A thermoplastic cover layer is laminated on either side by applying temperature and pressure to the reinforced foam core on the cover surfaces of the foam material in order to form the sandwich panel, wherein the cover layers are bonded to the reinforced foam core in a fused connection.

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.

A pouch (1) for semi-dense or liquid products and method for manufacturing are disclosed. The pouch (1) comprising a first half (5) and a second half (6) of a flexible sheet material, the flexible sheet material comprises at least an outer layer (10), a tie layer (15) and porous layer (20), the porous layer carrying at least partly a semi-dense or liquid product (25), whereby the first half (5) and the second half (6) form walls of the pouch, their respective porous layers (20) facing a product space formed by the first half (5) and the second half (6) and whereby a sealed seam (30) joins the first half (5) and the second half (6) of the flexible sheet material and peelably seals the pouch, the sealed seam (30) being formed by the tie layer (15) fully impregnating the porous layer (20) in the area of the sealed seam (30) forming a peelable seal.
