摘要： A thermally conductive composition contains a base polymer, an adhesive polymer, and thermally conductive particles. A thermal conductivity of the thermally conductive composition is 0.3 W/m·K or more. The thermally conductive particles include inorganic particles (a) with a specific surface area of 1 m2/g or less. The inorganic particles (a) are coated with the adhesive polymer. The production method includes a first mixing process of mixing the adhesive polymer and the inorganic particles (a) with a specific surface area of 1 m2/g or less so that the inorganic particles (a) are coated with the adhesive polymer, a second mixing process of adding and mixing the base polymer; and a curing process. Thus, the present invention provides a thermally conductive composition that has high thermal conductive properties, a high compression repulsive force, and less interfacial debonding resulting from stress, and a method for producing the thermally conductive composition.

摘要： A silicone laminate 1 includes layers of a silicone rubber layer (A) 2 and a silicone layer (B) 3 with a lower hardness than the silicone rubber layer (A) 2. The silicone layer (B) 3 is at least one layer selected from the group consisting of a silicone sponge layer (B1) and a silicone gel layer (B2). Both the silicone rubber layer (A) 2 and the silicone layer (B) 3 are made of a material that is converted to ceramic and forms a sintered body when burned, so that the material retains its shape. The silicone laminate 1 is fire resistant. It is preferable that the silicone rubber layer (A) 2 and the silicone layer (B) 3 are alternately stacked, and that the number of layers is two or more for each of the layers (A) and (B), and four or more in total. Thus, the silicone laminate has high fire resistance and high compressive resistance as a cushioning material for batteries.

摘要： A thermally conductive sheet 10 for a sealing product is configured to be disposed between a heat generating electrical or electronic component and a heat-dissipating case. The sheet has a Shore 00 hardness of 5 or more and 55 or less. The sheet is in the form of a frame having a space 11 in the frame. The space is configured to be filled with a thermally conductive liquid composition. In the heat generating electrical or electronic component of the present invention, the thermally conductive sheet 11 is attached between the component and the case. The space 11 being defined by the component, the case, and the thermally conductive sheet 10 is filled with the thermally conductive liquid composition. Thus, provided is a thermally conductive sheet for a sealing product that can prevent a thermally conductive liquid from leaking out even when the liquid is directly injected into a space between a heat generating electrical or electronic component such as a battery module and a case, that has a level of flexibility that puts no load on the heat generating electrical or electronic component, and that provides high adhesion between the component and the case. Also provided is a heat generating electrical or electronic component including the sheet.

摘要： A heat storage composition (20) of the present invention includes a matrix resin (21) and heat storage inorganic particles (22). The heat storage inorganic particles (22) are composed of a material that undergoes an electronic phase transition and has a latent heat of 1 J/cc or more for the electronic phase transition. The amount of the heat storage inorganic particles is 10 to 2000 parts by weight with respect to 100 parts by weight of the matrix resin. The heat conductivity of the heat storage composition is 0.3 W/m·K or more. The heat storage composition may further include heat conductive particles (23, 24). The heat storage inorganic particles are preferably metal oxide particles containing vanadium as the main metal component. The heat storage composition has high heat storage properties and high heat conduction properties, and is used as a heat storage silicone material provided between a heat generating component and a case. Since heat from the heat generating component is temporarily stored in the heat storage composition so that the heat conduction is delayed, the heat is diffused during the delay to eliminate partial heating, thereby resulting in uniform heat dissipation.

摘要： A magneto-rheological elastomer composition (10) includes a matrix resin (12) and a magnetic powder (11). The magnetic powder (11) is contained in an amount of 30 to 70% by volume based on 100% by volume of the composition. The magneto-rheological elastomer composition (10) has an Asker C hardness of 5 to 60 as determined by the Standard SRIS0101 of the Society of Rubber Science and Technology, Japan. The average particle size of the magnetic powder is preferably 2 to 500 μm, and the matrix resin is preferably an organopolysiloxane. The storage modulus of the magneto-rheological elastomer composition preferably changes by five times or more upon application of a magnetic force with a magnetic flux density of 200 mT. Thus, the present invention provides a magneto-rheological elastomer composition that greatly changes its storage modulus upon application of magnetism, a method for producing the same, and a vibration absorbing device including the same.
