HEAT-RESISTANT RELEASE SHEET AND THERMOCOMPRESSION BONDING METHOD
The heat-resistant release sheet of the present disclosure is a sheet including a sheet made of polytetrafluoroethylene (PTFE) or a modified PTFE, wherein the sheet is disposed between a compression bonding target and a thermocompression head at the time of thermocompression-bonding the compression bonding target by the thermocompression head to prevent fixation between the compression bonding target and the thermocompression head, and the content of a tetrafluoroethylene (TFE) unit in the modified PTFE is 99 mass % or more. The heat-resistant release sheet of the present disclosure can more reliably meet a demand for a shorter time (work time) required for thermocompression bonding.

METHOD FOR MANUFACTURING MOLDED ARTICLE
Provided is a method for manufacturing a molded article obtained by double belt press molding a thermosetting prepreg, in which the thermosetting prepreg is coated with a release film during molding, and a width of the prepreg is 1 to 25 mm smaller than that of the release film. This manufacturing method suppresses burr generation and fiber twisting, and is excellent in width restriction, and thus can be suitably used for, for example, automobile members, railroad vehicle members, aerospace machine members, ship members, household equipment members, sporting goods members, light vehicle members, building and civil engineering members, and housings for OA equipment and the like.

METHOD FOR MAKING ELASTOMERIC ARTICLES
A method for molding shaped silicone elastomeric articles from room temperature curable silicone compositions, which are practically not suited to being processed using extrusion techniques, is provided. The method enables the room temperature curable silicone composition to cure in a predefined shape (6) into which it is introduced to form a shaped silicone elastomeric article. The articles may be, for the sake of example, suitable for use as spacers for insulating glass units (IGUs).
