The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.

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 invention relates to highly elastic polyurethane foams which are suitable as functional materials having thermally insulating properties.

A formulation includes a polymeric material and can be used to form an insulated container.

A foam cushion pad formation assembly that includes a conveyance assembly having at least one moving conveyor component presenting a pad shape formation surface, which surface is convoluted and arranged to shape sealed enclosures of a pad chain received by the conveyance assembly. A separation device is provided to separate shaped pads of the pad chain received by said conveyor device. The shaped pads include convoluted surface that are formed by way of gripping projection and recesses combinations in the moving conveyor component. Embodiments include sensing for non separated pads from a downstream end of the bag chain, pad chain separation enhancement devices, and various control system including the requirement of confirmation of separation before feeding a new pad enclosure as in one containing liquid polyurethane precursor chemicals. An embodiment includes a pad chain path disruption sensor and a form feed control which implements the formation of pad enclosures free of filler material in a bridging region between the outlet end of the enclosure formation means and the conveyance assembly.

Foam items may be buffed using particles such as particulate sodium bicarbonate in accordance with the present invention. Foam items may be, for example, expanded EVA foam items pre-formed into an intermediate size and shape. A skin layer may be formed during the expansion of the foam item to form an expanded foam item which may be entirely or partially removed by buffing the item using particles projected with selected buffing parameters. The buffing parameters may be varied based upon the thickness of at least a portion of the skin layer and/or the desired degree of moldability for the foam item after buffing. Particulate sodium bicarbonate or other types of particles used for buffing may be recycled and reused for further buffing of foam items.

Prepare an extruded polystyrene foam that is characterized by being a singular polymer foam that is free of halogenated blowing agents, having a milled primary surface, having a width of 750 millimeters or more, and further characterized by having a ρ(CST/CSP) value that is 50 kilograms per cubic meter or less and a milled primary surface.

The present disclosure provides a polymeric membrane. The polymeric membrane includes a first thermoplastic elastomer layer. The thermoplastic elastomer layer includes a filler component that is at least about 30 wt % of the thermoplastic elastomer layer. The polymeric membrane can further include an optional second thermoplastic elastomer layer in contact with the first polyolefin layer.

The purpose of the present invention is to provide a method for manufacturing a solar cell module, comprising the steps of: placing a mixture solution comprising a polysiloxane and a curing agent in a humidified condition and sealing same; forming a polysiloxane film by curing the mixture solution; and manufacturing a porous polysiloxane film by evaporating water drops formed on the surface of the polysiloxane film. By applying the porous polysiloxane film manufactured by the present invention to a solar cell module, weight reduction and efficiency improvement effects of the solar cell module can be obtained.
