    摘要： A thermally conductive sheet having both of a high thermal conductivity and a high flexibility is obtained by providing a thermally conductive sheet including a composition containing: graphite particles (A) in the form of a scale, an elliptic sphere or a rod, a 6-membered ring plane in a crystal thereof being oriented in the plane direction of the scale, the major axis direction of the elliptic sphere, or the major axis direction of the rod; and an organic polymeric compound (B) having a Tg of 50° C. or lower, wherein the plane direction of the scale, the major axis direction of the elliptic sphere, or the major axis direction of the rod of the graphite particles (A) is oriented in the thickness direction of the thermally conductive sheet, the area of the graphite particles (A) exposed onto surfaces of the thermally conductive sheet is 25% or more and 80% or less, and the Ascar C hardness of the sheet is 60 or less at 70° C. Further there is provided a process for producing, without fail, a thermally conductive sheet advantageously for productivity, costs and energy efficiency and a radiator having a high heat radiating capability.

    摘要： A heat conducting sheet including a composition, wherein the composition contains plate-form boron nitride particles (A) having an average particle diameter of more than 10 μm and 60 μm or less, and an organic polymer compound (B) having a glass transition temperature (Tg) of 50° C. or lower, the plate-form boron nitride particles (A) are contained in the composition in an amount ranging from 45 to 75% by volume thereof, and are oriented to direct the major axis direction thereof along the thickness direction of the sheet. Thus, there is provided an electrically insulating and heat conducting sheet which can keep a high thermal conductivity while the sheet has additional properties such as flexibility.
