导热性片材
摘要：
本发明的课题在于提供一种可利用涂覆成型连续地制造并卷绕成卷状、并且具有高导热性和高绝缘性的片材。导热性片材是在经导热性树脂组合物填塞的玻璃布的两面或单面上具有导热性硅酮组合物固化而成的层的导热性片材，该导热性硅酮组合物包含硅酮成分和导热性填充材料（C），相对于该硅酮成分100质量份，该导热性填充材料（C）的量为1200～2000质量份，该导热性填充材料（C）具有不足15μm的平均粒径，该导热性填充材料（C）中，粒径为45μm以上的粒子的量为0～3质量%，并且粒径为75μm以上的粒子的量为0～0.01质量%。
摘要（英）：

The invention provides a sheet which can be produced continuously by coating molding, can be wound in a roll-like shape, and has high heat conductivity and high insulation properties. A heat-conductive sheet which comprises a glass cloth sealed with a heat-conductive resin composition and a layer arranged on both surfaces or one surface of the glass cloth and comprising a cured product of a heat-conductive silicone composition, wherein the heat-conductive silicone composition comprises a silicone component and a heat-conductive filler (C), the amount of the heat-conductive filler (C) is 1200 to 2000 parts by mass relative to 100 parts by mass of the silicone component, the heat-conductive filler (C) has an average particle diameter of less than 15 [mu]m, and the amount of particles each having a particle diameter of 45 [mu]m or more is 0 to 3% by mass and the amount of particles each having a particle diameter of 75 [mu]m or more is 0 to 0.01% by mass in the heat-conductive filler (C).
