Abstract: A provided heat-resistant cushioning sheet is a heat-resistant cushioning sheet configured to be disposed between a thermocompression face of a thermocompression apparatus and a target in thermocompression treatment of the target to prevent direct contact between the target and the thermocompression face, wherein a compression strain change amount ΔS250 being a difference S250−S25 between a compression strain S25 at 25° C. and a compression strain S250 at 250° C. is −5% or more. S25 and S250 are each a compression strain ST of the heat-resistant cushioning sheet evaluated by thermomechanical analysis (TMA), S25 is evaluated at an evaluation temperature of 25° C., and S250 is evaluated at an evaluation temperature of 250° C. The compression strain ST is determined by an equation ST=(t1−t0)/t0×100(%), where to is a thickness of the heat-resistant cushioning sheet at 25° C. and t1 is a thickness of the heat-resistant cushioning sheet.

Abstract: The polymer film of the present invention has through holes extending from one principal surface of the polymer film to the other principal surface of the polymer film. The through holes are straight holes having a central axis extending straight, and have a shape in which the area of a cross-section perpendicular to the direction of the central axis increases from the one principal surface of the polymer film toward the other principal surface. This polymer film has passages in its thickness direction, has an unconventional structure, and can be used in various applications, such as in a waterproof sound-permeable membrane, in a waterproof gas-permeable membrane, and in a suction sheet. The ratio a/b of the opening diameter a of the through holes at the one principal surface to the opening diameter b of the through holes at the other principal surface is 80% or is less than 80%.

Abstract: A provided heat-resistant cushioning sheet is a sheet configured to be disposed between a thermocompression face of a thermocompression apparatus and a target in a thermocompression treatment of the target, and includes: a substrate including a fluorine resin; and a coating layer including a heat-resistant resin and disposed on a one principal surface side of the substrate. One exposed surface of the heat-resistant cushioning sheet is formed by the coating layer. The heat-resistant resin is a resin other than a fluorine resin and has a melting point of 280° C. or higher and/or a glass transition temperature of 210° C. or higher. The provided heat-resistant cushioning sheet is well adapted to expected further increases in treatment temperature and pressure.

Abstract: A heat-resistant release sheet is configured to be disposed, when a resin or a target including a resin is used in a step involving heating and melting of the resin, between the resin or the target and a member to be brought into contact with the resin or the target to prevent direct contact between the resin or the target and the member. The sheet includes a skived sheet including polytetrafluoroethylene (PTFE) or a modified PTFE. A content of a tetrafluoroethylene (TFE) unit in the modified PTFE is 99 mass % or more. In each of two directions being in-plane directions of the heat-resistant release sheet and being perpendicular to each other, a rate of dimensional shrinkage induced by heating at 175° C. for 30 minutes is more than 0%. The sheet includes the skived sheet including the heat-resistant resin but prevents occurrence of problems attributable to inclusion of the skived sheet.

Abstract: The method of the present disclosure includes: (I) irradiating a polymer film (1) with an ion beam composed of ions (2) accelerated in a cyclotron so as to form a polymer film that has collided with the ions in the beam; and (II) chemically etching the polymer film formed in the irradiation (I) so as to form openings (4b) and/or through holes (4a) corresponding to tracks (3) left by the colliding ions in the polymer film. In the irradiation (I), a beam current value of the ion beam is detected upstream and/or downstream of the polymer film in a path of the ion beam, and an irradiation conditioning factor in the irradiation of the polymer film with the ion beam is controlled based on the detected beam current value so that the polymer film can be irradiated with the ions at a predetermined irradiation density. The method of the present disclosure is suitable for industrial production of porous polymer films.
