Title:
THERMALLY-CONDUCTIVE SHEET AND THERMALLY-CONDUCTIVE SHEET PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/264895
Kind Code:
A1
Abstract:
Provided is a thermally-conductive sheet having excellent adhesion to a heating body, and capable of suppressing excessive bleeding of a binder resin. The thermally-conductive sheet 1 comprises a cured product of a composition containing a binder resin 2, an anisotropic thermally-conductive filler 3, and another thermally-conductive filler 4 other than the anisotropic thermally-conductive filler 3, and satisfies conditions 1 and 2 below. [Condition 1] The tack force of the thermally-conductive sheet 1 is 80 gf or more. [Condition 2] With the thermally-conductive sheet 1 at a thickness of 1 mm and a size of 25 mm × 25 mm, and in a 40% compressed state, the amount of bleeding of the binder resin 2 after leaving the thermally-conductive sheet 1 for 48 hours at 125°C is 0.20 g or less.
