The restoration polyamide compound which shows water absortion power decrease (detailed description)

摘要

PROBLEM TO BE SOLVED: To provide a filling polyamide molding material, especially a polyamide molding material involving a medium filler ingredient.;SOLUTION: A thermoplastic polyamide molding material is suitable for producing, e.g., molded parts and other half-finished products or completed parts by extrusion molding, injection molding, pressure molding, direct processing, or direct compounding molding, and a compounded polyamide molding material is directly processed by injection molding or other molding methods. The polyamide molding material can be produced from a polyamide blend, e.g., by compounding with chopped fibers or endless fibers on a twin-screw extruder, has both a reduced water absorptivity and excellent mechanical characteristics, and yields highly excellent dimensional stability and change reduction of electrical characteristics of produced molding parts, such as an antenna housing for a static or mobile communication device.;COPYRIGHT: (C)2008,JPO&INPIT
