  • Patent number: 7175900
    Abstract: A cushioning and positioning pad has a body formed from superposed layers of resiliently compressible foam material and a reinforcing sheet embedded between adjacent layers. The reinforcing sheet is of such stiffness as to resist contraction along its length and width dimensions, but is resiliently bendable in response to the application of a force along its thickness dimension. The reinforcing sheet resists undesirable contraction lengthwise and widthwise of the pad when the latter is encapsulated in a curable coating of material which shrinks as it cures.

    Abstract: Disclosed is a method of manufacturing a mechanically and chemically embossed surface covering having selectively textured surfaces. The method includes forming a web coated with a wear layer. The coated web is heated to a temperature at which the wear layer is cured, the foam layer expands, and the pattern is chemically embossed to form a surface covering having foamed regions and nonfoamed regions. The temperature gradient of the surface covering is adjusted such that there is a temperature gradient difference between the foamed and nonfoamed regions. A surface texture is then mechanically embossed into the wear layer and selectively set onto the wear layer substantially overlying the non-foamed regions.

    Abstract: Selectivity embossed surface coverings are prepared by mechanically embossing a wear layer which overlays at least one printing ink containing a photoinitiator which has been printed in a pattern or design. The embossed wear layer is subjected to ultraviolet radiation which causes curing of the wear layer in the surface areas disposed over the printing ink. The product then is fused whereby the mechanical embossing in surface areas which are not disposed over the printing ink relaxes and becomes smooth. In a variant of the invention, a thermoplastic wear layer is employed which can be mechanically embossed in the surface areas which are not disposed over the printing ink with a texture different from the first applied mechanical embossing. In another variant, two different spectral regions of UV curing radiation are used so that a urethane coating can be employed as a top coat with a selectively embossed surface.

  • Patent number: 6936350
    Abstract: The present application relates to a white, biaxially oriented, flame-retardant, UV-resistant polyester film with at least one base layer which comprises, based on the weight of the base layer, from 2 to 60% by weight of a cycloolefin copolymer (COC), where the glass transition temperature of the COC is within the range from 70 to 270° C. The film also comprises from 0.01 to 5.0% by weight of a UV stabilizer as light stabilizer and also comprises from 0.5 to 30% by weight of flame retardant, based in each case on the weight of the layer comprising the UV stabilizer and/or comprising the flame retardant. The film of the invention is suitable for packing foods or other consumable items which are sensitive to light and/or to air, or for use in industry, e.g. in the production of hot-stamping foils or as a label film, or for image-recording papers, printed sheets or magnetic recording cards.

  • Patent number: 6908668
    Abstract: An object of the present invention is to provide a foamed polyolefin resin sheet which exhibits a high adhesive strength when laminated with a layer formed of a saponified ethylene-vinyl ester copolymer and which still exhibits a high adhesive strength even when laminated with a layer of a thermoplastic resin having relatively low polarity such as a polyolefin resin. This object is attained by a foamed polyolefin resin sheet including a foamed polyolefin resin layer and a non-foamed surface layer formed of a thermoplastic resin composition having an A1/A2 ratio falling within a range between 1×10?8 and 1×10?1, wherein A1 is a maximum absorbance of the infrared absorption spectrum of the thermoplastic resin composition within an infrared ray wave number region of from 1700 to 1750 cm?1 and A2 is a maximum absorbance of the infrared absorption spectrum of the thermoplastic resin composition within an infrared ray wave number region of from 1455 to 1465 cm?1.

  • Patent number: 6902799
    Abstract: A laminated sheet which contains a cross-linking foam material, and radiates far infrared so that it has heat-insulating and heat-retentive properties. The laminated sheet (1) has a three-layered structure including polyethylene foam (2) having a sheet shape that is one example of a cross-linking foam material in which a substance that radiates far infrared rays is mixed, non-woven fabric (3) having a sheet shape formed on a lower face thereof and a polyester film (4) formed on an upper face thereof. Since the laminated sheet of the present invention is allowed to radiate far infrared rays, it can greatly shorten the snow-melting time, etc., because of its heat reflection effects in comparison with a sheet made of a single material of non-woven fabric, and it also makes it possible to greatly improve heat-insulating and heat-retentive effects, and also to provide medical effects.

  • Patent number: 6899945
    Abstract: Buckyrock is a three-dimensional, solid block material comprising an entangled network of single-wall carbon nanotubes (SWNT), wherein the block comprises greater than 75 wt % SWNT. SWNT buckyrock is mechanically strong, tough and impact resistant. The single-wall carbon nanotubes in buckyrock form are present in a random network of individual single-wall carbon nanotubes, SWNT “ropes” and combinations thereof. The random network of the SWNT or SWNT ropes can be held in place by non-covalent “cross-links” between the nanotubes at nanotube contact points. In one embodiment, SWNT buckyrock is made by forming a SWNT-water slurry, slowly removing water from the slurry which results in a SWNT-water paste, and allowing the paste to dry very slowly, such that the SWNT network of the SWNT-water paste is preserved during solvent evaporation. Buckyrock can be used in applications, such as ballistic protection systems, involving light-weight material with mechanical strength, toughness and impact resistance.

  • Patent number: 6896954
    Abstract: An automobile trim has a trim body (a base layer) formed of a rubber composition and having a design surface, a decorating layer formed of a thermoplastic elastomer composition and thermally bonded integrally with the design surface of the trim body. A thermal bonding layer is formed of a thermoplastic resin composition and interposed between the decorating layer and the trim body so that the decorating layer is thermally bonded integrally with the trim body through the thermal bonding layer. The thermal bonding layer has a thickness to an extent not to prevent bending flexibility when the trim is attached to a vehicle body. In another example, a cushion layer is laminated on the trim body and formed of sponge rubber of EPDM, a decorating layer is laminated on the cushion layer and formed by foaming olefin thermoplastic elastomer, and an olefin bonding layer for bonding the cushion layer and the decorating layer.

  • Patent number: 6887060
    Abstract: A void filling device which facilitates insertion of a void filling material into a tubular component and hold of the void filling material therewithin. The device comprises a holder for void filling material which is designed to retain the void filling material to fill a void space by expanding with heat and is of a different material from the void filling material so as to be elastically deformed and inserted into the void space. When the cross-sectional configuration of the void space of the tubular component is a rectangle, the holder is formed into a plate-like configuration which is longer than the diagonal line of the rectangle and is adapted to be insertable into the void space by bending the same arcuately.

  • Patent number: RE39339
    Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria.
