    摘要： A thermally conductive sheet contains a matrix resin and thermally conductive particles. The content of the thermally conductive particles is 200 parts by volume or more with respect to 100 parts by volume of the matrix resin component. A polymer viscosity of the matrix resin component after a crosslinking reaction in the absence of the thermally conductive particles is 500 Pa·s or less at 25°C. A thermal conductivity of the thermally conductive sheet is 2.0 W/m·K or more. When the thermally conductive sheet with an initial thickness of 1.5 mm is compressed at a compression rate of 5.0 mm/min to measure a 50% compressive load value, the maximum load value is 100 kPa or more and the load value after 1 minute is more than 0 kPa and 100 kPa or less. With this configuration, the thermally conductive sheet has a high thermal conductivity, a low steady load value, and flexibility.

    摘要： A metal-integral conductive rubber component (10) of the present invention includes a laminate in which conductive rubber layers (1) and insulating rubber layers (2) are laminated alternately in parallel. The conductive rubber layers (1) and the insulating rubber layers (2) are integrated at their boundaries by cross-linking between the conductive rubber layers and the insulating rubber layers. The volume resistivity of the conductive rubber layers (1) is 10 -5 Ω·cm or more and 10 K Ω·cm or less. The volume resistively of the insulating rubber layers (2) is 1 M Ω·cm or more and 10 16 Ω·cm or less. A metal plate is integrated with at least one surface of the laminate that is perpendicular to the electric conduction direction via a conductive adhesive layer (3) made of conductive rubber. With this configuration, the metal-integral conductive rubber component can have high compression set properties, achieve a stable electric connection over a long period of time, be bonded to a printed wiring board, reduce in const, and improve the production efficiency.

    摘要： A thermally conductive composition comprises 100 parts by weight of a wax, 0 to 1000 parts by weight of a tackifier and 10 to 1200 parts by weight of a thermally conductive filler, and is a gel at room temperature or a sol at a high temperature of 35 to 100° C and is reversibly convertible in state. The composition is used for forming a thermally conductive film on a heat sink for use in electronic devices for releasing the heat generated by an electronic component of the device. Since the composition is in the form of a gel at room temperature, the thermally conductive film formed from the composition is unlikely to peel off easily, rendering the heat sink having the film formed thereon easy to handle. The film of the composition is converted to a sol with the heat generated by the electronic component in use, therefore completely fills up the clearance between the electronic component and the heat sink and becomes thinner, consequently diminishing the thermal resistance between the heat-generating electronic component and the heat sink and ensuring heat transfer from the component to the heat sink with an improved efficiency.

    摘要： A silicone gel sheet is heat-molded from a silicone gel composition comprising metal oxide magnetic particles and a thermoconductive filler. The sheet has a high electromagnetic wave absorbing property at a frequency ranging from 500 to 800MHz. The hardness of the composition after hardening treatment is set in the range of 10-95 when measured with an ASKER F-type hardness meter. The metal oxide magnetic particles used here can be either Mn-Zn ferrite or Ni-Zn ferrite whose average particle diameter is 1-50 µm. For the thermoconductive filler, a metal oxide, aluminum nitride, boron nitride, silicon nitride, or silicon carbide can be used. In the silicone gel molded sheet (1), an electroconductive mesh (3) is embedded in one surface layer of the silicone gel layers (2) while the other surface (4) is provided with adhesiveness. As a result, an electromagnetic wave absorbing thermoconductive silicone gel molded sheet is provided at a low cost, and the sheet is superior both in electromagnetic wave absorbing property and thermoconductivity.
