THERMAL CONDUCTIVE THERMOPLASTIC RESIN COMPOSITION HAVING EXCELLENT WATER-RESISTANCE AND ARTICLE USING THE SAME

摘要

PURPOSE: A thermoplastic resin composition and a molded product are provided to have an excellent heat conductivity and humid proof, mobility and industrially usable level of strength. CONSTITUTION: A thermoplastic resin composition comprises (a) 30-50 weight% of thermoplastic matrix resin, and (b) 50-70 weight% of silane group chemical surface processing magnesium oxide. The silane chemical is vinyl group or amine group containing silane oligomer. The thermoplastic matrix resin (A) is polyamide resin. The magnesium oxide (B) is in spherical particle and contains 80% or more of the total magnesium oxide weight with the average particle diameter of 30-80 micron, and has a specific surface area (BET) of 0.4-0.6 g / cm.
