HEAT CONDUCTIVE RESIN COMPOSITION FOR LED ILLUMINATION SUBSTRATE, METHOD FOR MANUFACTURING THE SAME, AND LED ILLUMINATION SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a heat conductive resin composition for LED illumination substrate, capable of improving heat conductivity and insulating properties regardless of the large amount of inorganic filler, such as magnesium oxide.;SOLUTION: In a heat conductive resin composition for LED illumination substrate containing a resin and inorganic filler, the inorganic filler contains at least a magnesium oxide, the content of the inorganic filler is ≥50 vol.% and 95 vol.% based on the total amount of the heat conductive resin composition for LED illumination substrate. A weight increasing ratio is 5% after a cured product of the heat conductive resin composition for LED illumination substrate being left for 500 hours under an atmosphere at 85°C of a temperature and 85% of relative humidity.;COPYRIGHT: (C)2014,JPO&INPIT
