ELECTRICALLY INSULATING AND HIGHLY THERMALLY CONDUCTIVE THERMOPLASTIC RESIN COMPOSITION AND HIGHLY THERMALLY CONDUCTIVE MOLDED ARTICLE

摘要

PPROBLEM TO BE SOLVED: To provide an inorganic material-containing thermoplastic resin composition having electrically insulating properties and excellent thermal conductivity. PSOLUTION: The thermoplastic resin composition having reduced thermal resistance at the interface of a highly thermally conductive inorganic compound and having high thermal conductivity while maintaining electric insulation properties at least contains a thermoplastic resin, the highly thermally conductive inorganic compound having ≥1.5 W/m K thermal conductivity as a simple substance and ≥0.1 Ωcm volume specific resistance, an electrically insulating low-melting point inorganic material having ≤350°C softening point. The molded article is molded out of the resin composition. A low-melting point glass having a specific composition is preferable as the electrically insulating low-melting point inorganic material having ≤350°C softening point. PCOPYRIGHT: (C)2008,JPO&INPIT
