THERMALLY CONDUCTIVE SHEET PRODUCT AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2023/286648

A1

The present invention provides: a thermally conductive sheet product wherein both surfaces of a fluorine rubber-based thermally conductive sheet are protected from foreign substances and the like, and excellent setting workability is achieved between a heat generation member and a heat dissipation member; and a method for producing this thermally conductive sheet product.　A thermally conductive sheet product which is obtained by bonding electrically insulating films to both surfaces of a thermally conductive sheet that is formed of a cured product of a thermally conductive fluorine-containing curable composition containing (A) a linear polyfluoro compound which comprises two or more alkenyl groups in each molecule, while having a perfluoro polyether structure in the main chain, (B) a fluorine-containing organohydrogen siloxane which comprises a perfluoroalkyl group or a perfluorooxyalkyl group in each molecule, or alternatively comprises a perfluoroalkylene group or a perfluorooxyalkylene group, while additionally containing two or more groups (SiH groups), wherein a hydrogen atom is directly bonded to a silicon atom, in each molecule, and which does not comprise an alkoxy group that is directly bonded to a silicon atom in the molecule, (C) a platinum group metal-based catalyst and (D) a specific amount of a thermally conductive filler.
