Patent number: 10352447Abstract: The gasket of the present invention is mainly comprised of a pressure-sensitive adhesive sheet containing a non-halogenated flame retardant, and at least one surface thereof is a pressure-sensitive adhesive face of the pressure-sensitive adhesive sheet containing a non-halogenated flame retardant. According to the present invention, a highly flame retardant gasket having practically sufficient tight-sealing property, which does not produce a toxic halogen gas during combustion can be realized. In addition, a highly flame retardant gasket having practically sufficient tight-sealing property, which does not produce a toxic halogen gas during combustion, and does not cause corrosion and discoloration of a metal member to be an adherend can be realized.Type: GrantFiled: December 28, 2010Date of Patent: July 16, 2019Assignee: NITTO DENKO CORPORATIONInventors: Ryuuichi Kabutoya, Hiroyuki Tsubaki

Publication number: 20110244230Abstract: A double-sided pressure-sensitive adhesive tape is used for fixing decorative panels and includes a pressure-sensitive adhesive layer containing bubbles and/or hollow microspheres. The pressure-sensitive adhesive layer is preferably formed from an acrylic pressure-sensitive adhesive, particularly an active-energy-ray-curable acrylic pressure-sensitive adhesive. The double-sided pressure-sensitive adhesive tape for fixing decorative panels preferably has a toluene emission of 15 ?g/g or less and preferably has a surface lightness L* of 60 to 30. The adhesive tape can be a double-sided pressure-sensitive adhesive tape for fixing decorative panels, which excels in conformability to curved surfaces and bumps, resilience resistance, and adhesiveness and which may thereby show excellent adhesive properties even when used for fixing a decorative panel to an adherend of a complicated shape with a curved surface or bumps or for fixing a narrow decorative panel to an adherend.Type: ApplicationFiled: November 25, 2009Publication date: October 6, 2011Applicant: NITTO DENKO CORPORATIONInventors: Hiroyuki Tsubaki, Shinji Inokuchi, Isao Hirose, Tokuhisa Kosaka

Publication number: 20110223380Abstract: A pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer containing a pressure-sensitive adhesive composition, a bubble, and a hollow inorganic fine particle. When a pinhole region is present in the pressure-sensitive adhesive layer where the light that has been radiated onto one surface of the pressure-sensitive adhesive layer is transmitted through the pressure-sensitive adhesive layer up to the other surface thereof, and when the pressure-sensitive adhesive tape is bisected with a line intersecting the longitudinal direction of the tape at right angles, 60% or more of large pinhole regions each having a diameter of 1.5 mm or more are present in either of the two portions. Thereby, when the pressure-sensitive adhesive tape is to be wound, the tape can be easily wound or it can be suppressed that the pressure-sensitive adhesive composition may be forced out.Type: ApplicationFiled: March 10, 2011Publication date: September 15, 2011Applicant: NITTO DENKO CORPORATIONInventors: Takuma OGAWA, Hiroyuki TSUBAKI, Shinji INOKUCHI, Tokuhisa KOSAKA, Tetsuya HIROSE

Publication number: 20110223379Abstract: A pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer as a pressure-sensitive adhesive containing a pressure-sensitive adhesive composition, a bubble, and a hollow inorganic fine particle. The hollow inorganic fine particle contains at least sodium and silicon, and the mass ratio of the sodium and the silicon that are contained in the hollow inorganic fine particle (Na/Si) is 0.5 or less. Thereby, the size of the pinhole and the number of the pinholes in the pressure-sensitive adhesive tape can be suppressed, the pinhole having a structure in which, when light is radiated onto one surface of the pressure-sensitive adhesive layer that is in the state of not being laminated on a substrate, the transmission amount of the light on the other surface thereof exceeds a predetermined threshold value, as a result of the presence of a bubble having a predetermined size or more in the pressure-sensitive adhesive layer.Type: ApplicationFiled: March 10, 2011Publication date: September 15, 2011Applicant: NITTO DENKO CORPORATIONInventors: Takuma OGAWA, Hiroyuki TSUBAKI, Shinji INOKUCHI, Tokuhisa KOSAKA, Tetsuya HIROSE

Publication number: 20110129661Abstract: A pressure-sensitive adhesive tape has a pressure-sensitive adhesive layer containing hollow inorganic fine particles and bubbles. The pressure-sensitive adhesive tape has a modulus at 100% of 13.0 N/cm2 or more and shear adhesive force of 80 N/cm2 or more. The hollow inorganic fine particles are hollow glass balloons. Thereby, the pressure-sensitive adhesive tape can be used in, for example, automobiles and buildings, etc., in which high shear adhesive force is required, and processability and workability can be improved because of a high initial elastic modulus thereof.Type: ApplicationFiled: November 29, 2010Publication date: June 2, 2011Applicant: NITTO DENKO CORPORATIONInventors: Hiroyuki Tsubaki, Shinji Inokuchi
