Publication number: 20130220677Abstract: Provided are a thermosetting adhesive composition excellent in storage stability, reliability, and low-temperature adhesion properties; and a curl-resistant heat-resistant film and a wiring film obtained using the composition. The thermosetting adhesive composition includes 100 parts by weight of a phenoxy resin having a bisphenol S skeleton in the structure thereof; 5 to 30 parts by weight of a maleimide compound containing a plurality of maleimide groups in the structure thereof; and 3 to 20 vol % of an inorganic needle-like filler. The heat resistant adhesive film is obtained by applying the thermosetting adhesive composition onto a polyimide film, followed by drying. The wiring film is obtained by placing a conductor wiring layer on the heat resistant adhesive film.Type: ApplicationFiled: February 19, 2013Publication date: August 29, 2013Applicants: Hitachi Cable Fine-Tech, Ltd., Hitachi Cable, Ltd.Inventors: Hitachi Cable, Ltd., Hitachi Cable Fine-Tech, Ltd.

Patent number: 8518839Abstract: The invention relates to a rolled product having a thickness that can be adjusted by means of separation. The inventive product comprises an alternating stack (2) of sheets (4) and layers (6) of an adhesive material (8). Each of said sheets (4) has an intrinsic resistance to tearing and each layer (6) of adhesive material (8) joins together two adjacent sheets (4) in the stack (2) using a bond strength that is lower than the tearing resistance of the sheets (4). In this way, each sheet (4) can be detached from the stack (2) without being torn. According to the invention, each sheet (4) is essentially made from woven fibers and each sheet (4) belonging to each pair of sheets (4) which are adjacent to the same layer (6) of adhesive material (8) is impregnated, throughout the thickness thereof, with a mass of adhesive material (8) which is incorporated in the shared layer (6) of adhesive material (8).Type: GrantFiled: September 16, 2002Date of Patent: August 27, 2013Inventor: Daniel André Gastel

Patent number: 8507084Abstract: A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.Type: GrantFiled: July 11, 2007Date of Patent: August 13, 2013Assignee: DuPont Teijin Films U.S. Limited PartnershipInventor: Fenghua Deng

Publication number: 20130199961Abstract: Disclosed is a cover film which is used in combination with a carrier tape and comprises at least a base layer, an intermediate layer, a releasing layer and a heat seal layer that is capable of being heat sealed to the carrier tape. The intermediate layer contains, as a main component, a linear low density polyethylene that is polymerized using a metallocene catalyst and has a tensile modulus of 200 MPa or less. The releasing layer contains a conductive material and also contains, as a main component, a hydrogenated resin of an aromatic vinyl-conjugated diene copolymer having an aromatic vinyl group content of 15-35% by mass. This cover film is small in variation in peel strength when the cover film is released, and is thus capable of suppressing troubles during the releasing in a mounting process.Type: ApplicationFiled: April 18, 2011Publication date: August 8, 2013Applicant: DENKI KAGAKU KOGYO KABUSHIKI KAISHAInventors: Akira Sasaki, Hisatsugu Tokunaga, Tetsuo Fujimura
