Abstract
Provided is a wholly aromatic liquid crystalline polyester resin compound having excellent electrical insulating properties, heat resistance, and mechanical strength due to the inclusion of an inorganic filler having low electrical conductivity, high heat resistance, and high mechanical strength.
Claims6
A wholly aromatic liquid crystalline polyester resin compound comprising:
- a wholly aromatic liquid crystalline polyester resin,
- a first inorganic filler having a surface resistivity of 1013Ω/sq or more, and
- a second inorganic filler having a surface resistivity of 1013Ω/sq or more and higher heat resistance (ASTM D648) and mechanical strength than those of the first inorganic filler,
- wherein the wholly aromatic liquid crystalline polyester resin compound has an arc resistance grade (ASTM D495) of 3 grade or lower and a heat resistance (ASTM D648) of 250° C. or more.
