THERMOCONDUCTIVE PRESSURE-SENSITIVE ADHESIVE COMPOSITION, THERMOCONDUCTIVE PRESSURE-SENSITIVE ADHESIVE SHEET AND ELECTRONIC PART

摘要

PROBLEM TO BE SOLVED: To provide a thermoconductive pressure-sensitive adhesive sheet endowed with thermoconductivity, flame retardancy, self-adhesive properties and insulating properties, a thermoconductive pressure-sensitive adhesive composition from which the sheet is obtained, and an electronic part equipped with the sheet.;SOLUTION: The thermoconductive pressure-sensitive adhesive composition (E1) comprises 100 pts.mass of at least one polymer (S1) selected from the group consisting of a rubber, an elastomer and a resin, at least 200 pts.mass and at most 900 pts.mass of an expanded graphite powder (B), at least 35 pts.mass and at most 250 pts.mass of a condensed phosphate ester (C), at least 15 pts.mass and at most 150 pts.mass of a phosphate salt (P) and at least 0.5 pt.mass and at most 200 pts.mass of a blowing agent (H), where the condensed phosphate ester (C) has a viscosity of at least 7,000 mPa s at 25°C and is always liquid under atmospheric pressure within a temperature range of 15 to 100°C. The thermoconductive pressure-sensitive adhesive sheet is composed of the thermoconductive pressure-sensitive adhesive composition (E1). The electronic part is equipped with the sheet.;COPYRIGHT: (C)2011,JPO&INPIT
