CONSTRUCTION BOARDS WITH COATED INORGANIC FACER
A construction board comprising (a) a foam core having a first planar surface and a second planar surface; (b) a facer, having first and second planar surfaces, including an inorganic fabric and a coating; and (c) an interfacial region between the foam core and said facer.
Roofing systems and methods
A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.
Anti-slip, noise reducing pad directly applied and adhered to the back of flooring materials and method
Flooring material has an anti-slip, noise reducing pad directly self-adhered to a bottom surface. The pad is formed by applying a foamable PVC material is directly on the bottom surface of the flooring and heating the PVC material to foam the PVC material. The PVC material may then be cooled to form the pad with a definite formed shape having a resilient outer surface layer and a spongy foamy inner structure.
METHODS OF MAKING CROSSLINKED POLYETHYLENE FOAM
Described herein are physically crosslinked, closed cell continuous foam structures comprising low density polyethylene (LDPE), linear low density polyethylene (LLDPE), or a combination of LDPE and LLDPE, and olefin block copolymer (OBC). The foam structure can be obtained by extruding a foam composition comprising LDPE, LLDPE, or a combination of LDPE and LLDPE, and OBC, irradiating the composition with ionizing radiation, and foaming the composition.
Foamed articles and methods of making the same
Foamed articles including a foamed thermoplastic elastomeric material, methods of making the foamed articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating such foamed articles are provided. In one aspect, a method for making a foamed article comprises placing an article comprising a foamable material and carbon dioxide in a vessel, maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material, optionally exposing the infused article to a second temperature and second pressure, and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.
Aircraft interior panels and methods of panel fabrication
A multifunctional fully integral panel system design, a unique material configuration, and a process for fabricating a net shape (or nearly net shape) panel in one production cycle. The panel may comprise a base facing with an outer perimeter, a decorative film applied to the exterior of the base facing, an aft facing having an outer perimeter fused to the base facing, and a reinforcement core disposed between the unfused portions of the base and aft facings, which reinforcement core also acts as acoustic insulation (i.e., a noise attenuator). Alternatively or additionally, a foam core or blanket having thermal and/or acoustic insulation properties is attached to the external surface of the aft facing. The fabrication process involves the application of different heat treatments to panel components having different forming temperature or rubbery/elastic plateaus.
THERMALLY EXPANDABLE SHEET AND THERMALLY EXPANDABLE SHEET PRODUCTION METHOD
A thermally expandable sheet includes:
a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material; and
a second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material,
wherein the second thermally expandable material further contains white pigment.
PASSENGER COMPARTMENT CARPET ASSEMBLY, AND METHOD FOR ASSEMBLING SUCH AN ASSEMBLY
The invention relates to a passenger compartment carpet assembly for a vehicle comprising a packing piece (10), a passenger compartment carpet (20) and expandable material (30) injected into a volume present in particular between said packing piece (10) and said passenger compartment carpet (20), the passenger compartment carpet having a lower surface (25) facing towards an upper surface (15) of said packing piece (10). The passenger compartment carpet assembly according to the invention is characterized in that the upper surface (15) of the packing piece (10), when in contact with the lower surface (25) of the passenger compartment carpet (20), includes a first plurality of channels (11) configured in such a way that said channels (11), when injected with expandable material (30), cause the formation of strips of dried expandable material ensuring that the passenger compartment carpet (20) is retained on the packing piece (10).
Composite materials
Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibers, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fiber; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.
Multilayer nonwoven fabric for foam molding
Multilayer nonwoven fabrics for foam molding that have excellent resistance to the separation of layers, have reinforcing effects and urethane leakage prevention performance, and are producible without the occurrence of fiber dust on the surface. In the multilayer nonwoven fabric for foam molding, a reinforcing layer is stacked on at least one side of a dense layer, the dense layer includes a meltblown nonwoven fabric layer (A) and spunbonded nonwoven fabric layers (B) that are stacked on both sides of the layer (A), and the meltblown nonwoven fabric layer (A) and the spunbonded nonwoven fabric layers (B) are partially thermocompression bonded with each other.
