Title:
HEAT TRANSFER SHEET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/185688
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat transfer sheet having exceptional flame retardancy and durability. This heat transfer sheet contains a fluororesin and expanded graphite, and exhibits thickness-direction thermal conductivity of 20 W/m•K or higher. In addition, this method for manufacturing a heat transfer sheet includes: a step for pressurizing a composition containing a fluororesin and expanded graphite, forming the composition into the form of a sheet, and obtaining a pre-heat-transfer sheet; a step for laminating a plurality of the pre-heat-transfer sheets in the thickness direction, or folding or winding the pre-heat-transfer sheet, to obtain a laminated body; and a step for slicing the laminated body at an angle equal to or less than 45° relative to the lamination direction, and obtaining a heat transfer sheet.
