摘要:
The present invention relates to a pressure-sensitive adhesive sheet, which includes a pressure-sensitive adhesive film including a base material layer and a pressure-sensitive adhesive layer disposed on at least one side of the base material layer, in which the base material layer includes a soft vinyl chloride resin and contains at least one compound selected from the group consisting of a fatty acid compound, an aliphatic metal salt and a phosphoric acid ester; and a release film including a liner base material and a release layer, in which a surface of the release layer in the release film has a surface free energy of 20 dyn/cm or more but less than 30 dyn/cm, in which the release film and the pressure-sensitive adhesive film are laminated in such a way that the release layer side of the release film is in contact with a surface of the pressure-sensitive adhesive layer. The pressure-sensitive adhesive sheet has a high expandability, shows no transfer of deposits from the base material onto an adherend and is useful as a sheet for holding semiconductor wafers, electronic parts and so on.

An adhesive transfer device and method for selectively making a repositionably adherable substrate from a selected substrate are disclosed. The device comprises a base substrate, a layer of repositionable adhesive disposed on the base substrate, a layer of permanent adhesive adjacent to the repositionable layer opposite the base substrate, and structure providing a release surface. The base substrate and the structure providing the release surface can be moved apart so as to leave both of the adhesive layers on the base substrate with the permanent layer exposed, thereby enabling the selected substrate to be adhered to the exposed permanent layer. The base substrate and the selected substrate can be moved apart from one another so as to separate the base substrate from the repositionable layer and leaving both the adhesive layers on the selected substrate with the repositionable layer exposed, thereby allowing the selected substrate to be repositionably adhered.

The present invention relates to a pressure-sensitive adhesive sheet for dicing, which comprises a substrate and at least one pressure-sensitive adhesive layer disposed on at least one surface of the substrate, the substrate containing polyvinyl chloride as a primary component and a trialkyl phosphite as a thermal stabilizer of the polyvinyl chloride, and the pressure-sensitive adhesive layer containing poly(meth)acrylic acid ester as a primary component, in which the trialkyl phosphite transited from the substrate into the pressure-sensitive adhesive layer is not unevenly distributed on a surface of the pressure-sensitive adhesive layer; a method of processing a processed material using the same, and a piece of a processed material obtainable by the method.
摘要:
Flexible, conformable, pressure sensitive adhesive film material has a plastic film and a compatible pressure sensitive adhesive layer on at least a first surface of the plastic film. The plastic film is formulated of plastic film polymers and optional additives. The plastic film polymers include, at least, thermoplastic ethylene/styrene interpolymer in major part, and a temperature modifier polymer, which increases the thermal resistance of the plastic film. The pressure sensitive adhesive layer is compatible with the plastic film, such as acrylic-based adhesive and shear-coated rubber-based adhesive. The PSA film material can be harness tape for use in wire harness constructions and can provide advantageously low fogging and good recyclability, along with performance characteristics suitable to stringent harness tape and other end-use applications. In certain embodiments, a plastic barrier layer is coextruded with the plastic film, and a surface of the plastic film opposite the adhesive layer.

摘要:
A breathable film cover for transparent plastic plates (12) employed as windows and the like. A metalized plasticized polyvinyl chloride film (18) is adhesively laminated to a polycarbonate or polyacrylate plate by means of an adhesive (16) having a UV absorber. The plasticized PVC film allows for the escape of moisture emanating as a result of degasification of the polycarbonate or polyacrylate plates. The permeability of the PVC or polyvinyl chloride film to moisture allows the metalized plasticized polyvinyl chloride film to remain adhered to the plates without bubbles, craters or tunnels.
