Abstract:
Described herein is a polyamide composition comprising two polyamides and glass fiber, wherein one of the polyamides is a polyphthalamide formed by polycondensation from various monomers: dicarboxylic acid(s) with diamine(s) and/or amino acid(s), wherein at least one monomer contains a cyclohexyl group. It was surprisingly discovered that the polyamide composition has improved warpage and/or mold shrinkage properties, excellent mechanical performance and high Tg and/or Tm. Due to the excellent performance, the polyamide composition is suitable for molding and can be desirably incorporated into mobile electronic device applications.
Abstract:
A thermally conductive filler can exhibit high thermal conductive properties with a reduced specific gravity, a thermally-conductive composite material and a wire harness contains such a thermally conductive filler, and a method manufactures a thermally conductive filler. A thermally conductive filler contains base particles and a coating layer coating the particles, the coating layer contains a gel-like substance that is bonded to the surfaces of the base particles through chemical bonding and coats the surfaces of the base particles, and a thermally-conductive substance that is dispersed in the layer of the gel-like substance and has a higher thermal conductivity and a larger specific gravity than the base particles and the gel-like substance. Also, a thermally-conductive composite material is obtained by dispersing the thermally conductive filler in a matrix material. Furthermore, a wire harness contains the thermally-conductive composite material.
