WHOLLY AROMATIC LIQUID CRYSTALLINE POLYESTER RESIN COMPOUND WITH ENHANCED ELECTRICAL INSULATING PROPERTY

摘要

PURPOSE: A wholly aromatic liquid crystal polyester resin compound is provided to have excellent electric insulation property, heat resistance, and physical strength by comprising an inorganic filler, which has low electric conductivity, and excellent heat resistance and physical strength. CONSTITUTION: A wholly aromatic liquid crystal polyester resin compound comprises: a wholly aromatic liquid crystal polyester resin; a first inorganic filler, of which surface resistance is 10^13 Ω/sq or greater; and a second inorganic filler, of which surface resistance is 10^13 Ω/sq or greater, and heat resistance(ASTM D648) and physical strength are higher than the first inorganic filler. An arc resistance class(ASTM D495) is 3 class or less, a heat resistance(ASTM D648) is 250°C or greater. The first inorganic filler comprises at least one selected from the group consisting of muscovite, talcum and wollastonite.
