LIQUID CRYSTAL POLYMER COMPOSITION WITH EXCELLENT ELECTROMAGNETIC PROPERTY AND INSULATING PROPERTY AND MOLDED ARTICLES THEREOF

摘要

PURPOSE: A liquid crystal polymer composition is provided to ensure excellent electromagnetic shielding property and insulating property and to prepare molded articles with excellent electromagnetic shielding property and insulating property since the liquid crystal polymer composition is easily granulated.;CONSTITUTION: A liquid crystal polymer composition comprises: a liquid crystal polymer; and magnetic filler formed by heat-treating a ceramic powder and a soft magnetic metal powder in an inert gas atmosphere. The liquid crystal polymer is wholly aromatic liquid crystal polyester. The ceramic powder includes silicon oxide as a main component. The soft magnetic metal powder includes iron or iron alloy as a main component. The aspect ratio of the soft magnetic metal powder is 2 or greater.;COPYRIGHT KIPO 2012
