摘要： The present invention relates to filled polyamide molding materials, in particular polyamide molding materials with medium filler content, which 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.The thermoplastic polyamide molding materials according to the present invention 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.
摘要翻译：本发明涉及填充的聚酰胺成型材料，特别是具有中等填料含量的聚酰胺成型材料，其可由聚酰胺共混物生产，例如通过在双螺杆挤出机上与短切纤维或环状纤维复合，并且具有还原水吸收和良好的机械性能，这导致非常好的尺寸稳定性和减少所制造的模制部件（例如固定或移动通信装置的天线外壳）的电气特性的变化。根据本发明的热塑性聚酰胺成型材料分别适用于例如通过挤出，注射成型，压制，直接加工或直接混合来制造模制零件和其它半成品或成品，其中复合的聚酰胺成型材料是通过注射成型或其他成型方法直接加工。
