| 20110298152 | Thermoplastic Fiber Material Spun from a Raw Material Containing Polyhydroxyether, Methods for Its Production and Uses for It - The invention describes a new synthetic fiber material of polyhydroxyether, as well as a melt-spinning method for its production. The new material can be used, in particular, for stabilization of the reinforcement fibers of high-performance fiber composite materials before they are embedded in the matrix material. During this usage, the polyhydroxyether fiber material dissolves at a temperature above its glass transition temperature entirely in the matrix material, so that the reinforcement fibers can be arranged largely free of kinking. In addition, it forms cross-links with the matrix material to form a homogeneous matrix and thus does not constitute a disruptive third phase in the composite material. The compatibility of the matrix and reinforcement fiber is also improved. It was possible to improve the bending strength of test slabs by 12% as compared to that of reference slabs with polyester filament. | 12-08-2011 |
| 20110293868 | THERMOPLASTIC POLYAMIDE MOULDING COMPOSITIONS - The invention relates to thermoplastic polyamide moulding compositions containing: (A) at least 20% by wt. polyamide and/or at least one copolymer containing at least 20% by wt. polyamide structural units; (B) 0.01% by wt. to 2% by wt., relative to the polyamide portion and/or the portion of polyamide structural units, of the composition of a copper-containing stabiliser; and (C) 0.01% by wt. to 3% by wt., relative to the polyamide portion and/or the portion of polyamide structural units of the composition, of at least one organic compound containing metal complexing groups, so that the copper ions are present in complexed form through binding to the metal-complexing groups.

| 20110217495 | POLYAMIDE MOULDING MATERIALS FOR THE PRODUCTION OF MOULDED ARTICLES HAVING REDUCED SURFACE CARBONIZATION - Moulded articles having reduced surface carbonization and longer retention of the mechanical properties and methods of producing same are presented. In an embodiment, the moulded article comprises polyamides with nanofillers, which can be produced by means of injection moulding or extrusion, in particular by extrusion blow moulding, coextrusion blow moulding or sequential blow moulding with and without 3D hose manipulation. For example, the polyamide moulding materials for the production of moulded articles have reduced surface carbonization in the moulded articles in subsequent long-term use at elevated temperatures. | 09-08-2011 |
| 20110039979 | FILLED POLYAMIDE MOLDING MATERIALS SHOWING A REDUCED WATER ABSORPTION - Filled polyamide molding materials, in particular polyamide molding materials with medium filler content, are producible from a polyamide blend and for example by compounding with chopped or endless fibers on two-screw extruders, and have a combination of reduced water absorption and good mechanical properties, which results in very good dimensional stability and reduced variation of the electrical properties of the produced molded part, such as an antenna housings of stationary or mobile communication devices. These thermoplastic polyamide molding materials are suitable for manufacturing molded parts and other semi-finished or finished parts, for example by extrusion, injection molding, pressing, direct process or direct compounding, respectively, wherein the compounded polyamide molding material is directly processed by injection molding or other shaping methods. | 02-17-2011 |
