摘要:
A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

摘要:
An expandable laminate, comprising at least two paper layers and at least one intermediate expandable layer, said expandable layer comprising expandable particles, which are in an unexpanded state, and each side of the expandable layer being attached to a surface of one of the at least two paper layers by an adhesive coating that has been applied onto the paper layer surface, thus leaving the expandable layer substantially free from adhesive, an expanded laminate, obtained by heat treatment of said expandable laminate, a process for forming the laminate comprising the steps of applying an adhesive to one side of a first paper layer to form an adhesive coating; applying dry expandable particles, which are in an unexpanded state, onto the first paper layer;removing any surplus of expandable particles not being adhesively attached to the first paper layer; applying an adhesive to one side of a second paper layer to form an adhesive coating; assembling the first and second paper layers so that the expandable particles are positioned between the paper layers, thus forming an intermediate expandable layer, and the of the laminate in the manufacture of packages or containers, or in the manufacture of building panels.

A method (401) of repairing a core stiffened structure, including removing (403) a damaged portion of the core stiffened structure; bonding (407) a shelf (701) onto a first core member (217); bonding (411) a second core member (1103) to a shelf (701); and securing (413) a skin patch over the second core member (1103).
摘要:
A continuous process for preparing insulation panels having thick (0.2 mm to 1 mm) metal facing panels and a fiber-reinforced polymer foam core is disclosed. In the process, a bottom metal facing panel (2) is continuously supplied. A mat (10) of reinforcing fibers and a foamable resin composition (19) are applied to the bottom facing panel. A flexible barrier layer (5) is applied atop the foamable resin composition, and the assembly is passed through nip rolls (12,13) to compress the assembly and force the resin composition into the fiber mat. An adhesive layer (4) and top metallic facing layer (1) are then applied on top of the flexible barrier layer, and the resulting assembly is gauged and cured by passing it through a double band laminator (11).
摘要:
Die Erfindung betrifft ein Verpackungsmaterial für korrosionsanfällige Gegenstände aus Metall. Das Verpackungsmaterial weist eine Barriereschicht (2) aus einem ersten Kunststoff, eine innenseitige Transferschicht (3) und eine zwischen der Barriereschicht (2) und der Transferschicht (3) angeordnete Reservoirschicht (4) aus einem geschäumten Kunststoff auf, wobei in der Reservoirschicht (4) ein flüchtiger, korrosionsinhibierender Wirkstoff enthalten ist und wobei die Barriereschicht 2 eine geringere Durchlässigkeit für den korrosionsinhibierenden Wirkstoff als die Transferschicht (3) aufweist. Das Verpackungsmaterial ist eine Coextrusionsfolie. Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung des Verpackungsmaterials.
摘要:
A polyurethane foam sheet which is applicable to artificial leathers, synthetic leathers, cushioning materials, and the like for use in various applications; and a process for producing a layered sheet which comprises using the polyurethane foam sheet. The polyurethane foam sheet is produced by mixing a thermally molten hot-melt urethane prepolymer (A) having an isocyanate group at a molecular end with a compound (B) having at least two groups having active hydrogen to obtain a liquid mixture, applying the liquid mixture in a sheet form to a substrate, and bringing the sheet-form liquid mixture obtained into contact with water vapor or moisture (water) to foam the liquid mixture by the action of water. A third substrate is laminated to the polyurethane foam sheet to produce a layered sheet.
摘要:
A foamed layer-laminated film or sheet having a foamed layer of a thermoplastic resin laminated on a base material such as a paper or PET, and is useful as a material for producing formed articles such as paper containers, aluminum foil containers, packing films and sheets for containing high-temperature foods, beverages and the like owing to its enhanced heat-insulating property. The foamed layer has innumerable fine elongated foamed cells, and local shades of distribution density of the cells create an appearance of vertical striped patterns on a frosted-glass-like translucent background lending the laminated film or sheet well for use as a material for ornamental articles. The invention further provides a process for easily producing the film or sheet maintaining good productivity at a low cost. The laminated film or sheet includes at least a base material and a thermoplastic foamed resin layer, the foaming layer being foamed at the time of extruding a thermoplastic resin composition containing a foaming agent so as to be laminated on the base material.
