Abstract: A liquid-crystalline polymer composition containing a liquid-crystalline polymer and a magnetic filler formed by heat-treating a composite material of a ceramic powder and a soft magnetic metal powder in an inert gas atmosphere.

Abstract: The present invention provides a resin composition comprising (A) a thermoplastic resin, (B) alumina fine particles and (C) a plate-like filler, wherein the component (B) is contained in the larger amount than the amount of the component (C) in the composition, and the resin composition has a specific volume resistance of 1×1010 ?m or more.

Abstract: The present invention provides a resin composition comprising: (A) a thermoplastic resin, (B) a granular material which has a number average particle diameter of 0.5 to 5 mm and is obtainable by granulating a fiber mainly having alumina with a number average fiber diameter of 1 to 50 ?m, and (C) a filler composed of a material of which electric resistivity at 300 K is 102 ?m or less. The resin composition can be molded into a molded article with electric insulation. The electric resistivity of the molded article has sufficient electric insulation in applications such as in electric and electronic parts.

Abstract: A thermal-conductive resin composition which can provide an molded article excellent in thermal conductivity and/or mechanical strength is provided. The resin composition comprising a resin selected from a thermosetting resin and a thermoplastic resin; a granule having a number average particle diameter of 0.5 to 5 mm and comprising alumina fibers with a number average fiber diameter of 1 to 50 ?m; and an alumina fine particle.

Abstract: Granules useful for highly thermal-conductive resin composition are provided.
