THERMALLY CONDUCTIVE PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet which has thermal conductivity and excellent electrical insulating properties even when thermally conductive particles are contained in a pressure-sensitive adhesive layer.SOLUTION: The thermally conductive pressure-sensitive adhesive sheet of the present invention has an acrylic pressure-sensitive adhesive layer which contains a phosphate ester-based dispersant containing a phosphate triester and thermally conductive particles. The thermally conductive particles are at least one selected from the group consisting of aluminum hydroxide particles and alumina particles. The content of the thermally conductive particles is preferably 40 to 75 vol.% inclusive based on the total volume (100 vol.%) of the acrylic pressure-sensitive adhesive layer.
