Abstract: A member supplying sheet provided includes: a protective cover member configured to be placed on a face of an object to prevent a foreign matter from entering an opening of the face; and a substrate sheet having a surface where the protective cover member is placed. The protective cover member includes a laminate including: a protective membrane having a shape configured to cover the opening when the protective cover member is placed on the face; and an adhesive layer. The protective cover member is placed on the surface of the substrate sheet via the adhesive layer. The member supplying sheet is suitable for supplying the protective cover member to a device that picks up the protective cover member in a state where the substrate sheet is pushed up from a back side of the substrate sheet, the back side being opposite to the surface.

Abstract: Provided is a pressure-sensitive adhesive (PSA) sheet having a low relative dielectric constant, satisfactory metal corrosion preventing property, and excellent member holding performance. The present invention provides a PSA sheet having a PSA layer including a base polymer and a rust inhibitor. The base polymer is an acrylic polymer, and monomeric components constituting the acrylic polymer comprise a (meth)acrylate having an alkyl group having 5 or more carbon atoms at an ester end at 50% by weight or more of the monomeric components. The PSA layer has a relative dielectric constant of 3 or less at 300 kHz.

Abstract: A member of the present invention is to be placed to cover a ventilation hole in order to allow passage of gas between an outside and an inside of a housing through the ventilation hole of the housing and prevent dust and/or a liquid from entering the inside from the outside through the ventilation hole. The member of the present invention includes a porous membrane having air permeability in a thickness direction and a provisional protective film joined to the porous membrane to cover the porous membrane from the outside side. The provisional protective film is air-impermeable in a thickness direction or has lower air permeability in the thickness direction than the air permeability of the porous membrane. The provisional protective film and the porous membrane are joined to each other in such a manner that the provisional protective film is removable from the porous membrane.

Abstract: An adhesive tape substrate production method disclosed in the present description includes the steps of: decreasing the amount of a sizing agent contained in a glass cloth by heat; impregnating the glass cloth for which the amount of the sizing agent has been decreased with a dispersion of a fluorine resin; and heating the impregnated glass cloth to a temperature equal to or higher than a melting point of the fluorine resin. Thus, an adhesive tape substrate including the glass cloth impregnated with the fluorine resin is obtained. This method are more productive of adhesive tape substrates and adhesive tapes than conventional methods. In addition, adhesive tape substrates and adhesive tapes for which the occurrence of defects in appearance are reduced can be produced.

Abstract: A silicone adhesive composition includes 100 parts by weight of a peroxide-curable silicone, 1.2 to 3.2 parts by weight of an organic peroxide curing agent, and 2 to 9 parts by weight of an addition reaction-curable silicone rubber. An adhesive tape includes a base and an adhesive layer placed on the base, the adhesive layer being formed from the above silicone adhesive composition. The adhesive composition exhibits high load bearing capacity even in higher-temperature environments than ever before. The adhesive tape exhibits high load bearing capacity and good shelf life even in such high-temperature environments.
