Patent number: 8696958Abstract: A manufacturing process is disclosed that allows molded planar products such as solid interior and entry doors to be produced by molding lignocellulosic and cellulosic composite materials. The doors can be manufactured by compressing and heating a layered mixture of fine wood particles blended with thermo-set molding resins and coarse wood particles blended with thermo-set binding resins between two open molds. The molded door is then removed from between the molds and trimmed to the finished size.Type: GrantFiled: December 18, 2009Date of Patent: April 15, 2014Assignee: Flowery BranchInventor: David W. Moeller

Publication number: 20140087187Abstract: Cultured stone materials, and products including the same, have a plastic component and particulate calcium sulfate filler, which may be a calcium sulfate filler in the form of calcium sulfate dihydrate filler that provides fire retardancy, and the filer provides other processing and product benefits. The cultured stone materials may be made by converting a mixture of a plastic component and particulate calcium sulfate filler to a rigid shaped form.Type: ApplicationFiled: May 27, 2012Publication date: March 27, 2014Applicant: AMERICAN SELENITE, LLCInventor: George C. Hawley

Patent number: 8236430Abstract: Composites are described, comprising polyacetal and at least one thermoplastic polyamide elastomer formed by a polyacetal molding which has been partially or completely coated with the thermoplastic polyamide elastomer or onto which one or more moldings composed of the thermoplastic polyamide elastomer have been directly molded. The composites are characterized in that the polyacetal and the thermoplastic polyamide elastomer have been bonded adhesively or cohesively to one another via injection of the polyamide elastomer onto the polyacetal molding, and in that the tensile bond strength between the polyacetal and the thermoplastic polyamide elastomer is at least 0.5 N/mm2. The composites may be used as connectors, as functional components with integrated sealing properties and/or with integrated damping properties, or else as non-slip and easy-grip elements.Type: GrantFiled: December 22, 2004Date of Patent: August 7, 2012Assignee: TICONA GmbHInventors: Ursula Ziegler, Frank Reil, Klaus Kurz

Patent number: 7413697Abstract: Methods for making processable rubber compositions containing fluorocarbon elastomers cured by polyol or phenol curative agents include an optional heat treating step before thermoplastic processing. In one aspect, a dynamic vulcanizate of a fluorocarbon elastomer containing an excess of un-reacted polyol curative agent is subject to a pre-molding heat treatment at a temperature of 150° C. or above, but preferably below the thermoplastic processing temperature, for a time sufficient to drive off or decompose at least part of the un-reacted or excess polyol curative agent. After part or all of the curative agent is driven off or decomposed by the heat treatment, the heat treated material may be thereafter processed by thermoplastic techniques to form shaped articles. Advantageously, articles produced by thermoplastic processing of the heat treated dynamic vulcanizates are characterized by a low permeability to gases and vapors.Type: GrantFiled: June 21, 2004Date of Patent: August 19, 2008Assignee: Freudenberg-NOK General PartnershipInventor: Edward Hosung Park

Patent number: 6558595Abstract: The present invention relates to a process for producing close-to-final-shape moldings from pressing compositions, in which reinforcing fibers, fiber bundles, fiber fabrics, fiber mats and/or random fiber agglomerates based on metal, glass, carbon, nitrogen, silicon and/or boron, one or more binders and, if desired, one or more additives or fillers are mixed to give a pressing composition and pressed in a pressing mold under the action of pressure to give a molding, where a curable carbonizable polymer is used as binder. The invention provides for a cold-curing binder to be used and the curing reaction to be initiated by addition of a catalyst, with pressure only being applied after the curing reaction has commenced.Type: GrantFiled: October 2, 2000Date of Patent: May 6, 2003Assignee: DaimlerChrysler AGInventor: Wolfgang Lotz

Patent number: 6500371Abstract: The invention relates to a continuous process for preparing aminoplastics and/or phenolics, in which a precondensate solution is prepared in a first extruder (14), the precondensate solution is continuously fed, with addition of additives, to a second extruder (20) with partial filling in the feed section (E) and devolatilization section (G), devolatilized in the second extruder (20) and then formed to give a molding composition or an end product. The process is particularly suitable for preparing melamine resins, in particular melamine-formaldehyde resins, as well as for preparing urea-formaldehyde resins.Type: GrantFiled: February 7, 2000Date of Patent: December 31, 2002Assignee: BASF AktiengesellschaftInventors: Heinz Berbner, Hans Etling, Erhard Guenther, Tilman Sirch, Hans Dieter Zettler
