摘要： The present invention provides a thermally-conductive sheet excellent in heat dissipation properties. The thermally-conductive sheet includes a polymer matrix and a thermally-conductive filler dispersed in the polymer matrix. The present invention is a thermally-conductive sheet including a polymer matrix and non-spherical particles of a thermally-conductive filler that are dispersed in the polymer matrix. At least a part of the thermally-conductive filler particles are oriented in a thickness direction of the sheet. When a portion of the sheet where the thermally-conductive filler particles have the highest degree of orientation in the thickness direction of the sheet is defined as a center of orientation, and an axis passing through the center of orientation and perpendicular to sheet surfaces is defined as a central axis of orientation, the thermally-conductive sheet has a region where the thermally-conductive filler particles are oriented toward one point on the central axis of orientation and where the degree of orientation of the thermally-conductive filler particles in the thickness direction of the sheet decreases from the center of orientation toward a periphery of the sheet.

摘要： A disclosed method for producing an elongated filler-containing fluororesin sheet includes: a step (I) of forming a strip member from a strip sheet containing a fluororesin, a filler, and a forming aid; and a step (II) of forming an elongated sheet strip by rolling the strip member in a longitudinal direction of the strip member. In the step (I), the strip member is formed by bending the strip sheet in such a manner that quadrilaterals formed on a surface of the strip member, each defined by two strip member side edges extending in the longitudinal direction of the strip member and two strip sheet side edges of the strip sheet that crosses a region between the two strip member side edges are parallelograms each having an acute angle α as an interior angle and that the parallelograms are arranged in the longitudinal direction of the strip member.

摘要： An adhesive tape includes: a substrate made of a fluorine resin; and a silicone-based adhesive agent layer disposed on one surface of the substrate. The adhesive tape has a thickness of 50 μm or more. An adhesive strength of an adhesive surface to the other surface of the substrate after a friction test is 4.0 N/19 mm or more. The friction test is performed according to a test method for coefficient of friction specified in JIS K7125: 1999, and performed in a state where: a contact surface, of a sliding piece used in the test method, brought into contact with a surface to be tested is covered with a single fiber cloth (cotton, for friction) specified in JIS L0803: 2011; the other surface of the substrate is defined as the surface to be tested; and the number of times of reciprocation is set to 10 times.
