Latest Patents

One of Maruyama's latest patents is a heat conductive sheet. This innovative sheet comprises a cured product layer of a heat conductive silicone composition on one or both surfaces of a glass cloth. The glass cloth is sealed using a cured product of a heat conductive resin composition. The heat conductive silicone composition includes an organic silicon compound component and an aspherical heat conductive filler. The amount of the heat conductive filler ranges from 250 to 600 parts by mass with respect to 100 parts by mass of the organic silicon compound component. Notably, the heat conductive filler has a DOP oil absorption of not more than 80 ml/100 g. This heat conductive sheet can be continuously manufactured by coating molding and can be wound into a roll, even with the use of an inexpensive aspherical heat conductive filler. It boasts high heat conductivity, low thermal contact resistance, and excellent insulating properties.

Another significant patent is a thermally conductive sheet. This sheet includes a glass cloth filled with a thermally conductive resin composition. One or both surfaces of the glass cloth are layered with a cured, thermally conductive silicone composition. The thermally conductive silicone composition comprises a silicone component and thermally conductive filler (C) in an amount of 1,200 to 2,000 parts by mass, relative to 100 parts by mass of the silicone component. The thermally conductive filler (C) has an average particle size smaller than 15 µm, with an amount of particles having a particle size of 45 µm or larger being 0 to 3 mass %, and an amount of particles having a particle size of 75 µm or larger being 0 to 0.01 mass %, based on the amount of the thermally conductive filler (C).
