  • Vacuum thermal insulating material and thermal insulating box including the same
    Patent number: 8617684
    Abstract: There are provided a vacuum thermal insulating material that is excellent in terms of a handling property, a thermal insulating property, creep resistance, and productivity; and a thermal insulating box including the vacuum thermal insulating material. A core material was enclosed and sealed in a wrapping material with a gas barrier property. The core material of the vacuum thermal insulating material in which the interior of the wrapping material is in a decompression state, is constituted by one organic fibrous assembly having continuous organic fibers formed sheet-shaped or a stack of the organic fibrous assemblies.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: December 31, 2013
    Assignee: Mitsubishi Electric Corporation
    Inventors: Kyoko Nomura, Syuichi Iwata, Tsukasa Takagi, Hideaki Nakano, Yosuke Fujimori, Masanori Tsujihara, Nobuo Yamamoto, Syohei Abiko

  • Heat insulating box
    Patent number: 5985393
    Abstract: A heat insulating box, such as a refrigerator box, comprises a heat insulator and a box member that is in contact with the heat insulator. The heat insulator is formed of a urethane foam using either HCFC-123 (CHCl.sub.2 CF.sub.3) or HCFC-141b (CH.sub.3 CCl.sub.2 F) or both as a forming agent, and the box member is formed of a styrene/acrylonitrile/butadiene terpolymer, a styrene/ethylene-.alpha.-olefinic rubbery copolymer/acrylonitrile terpolymer (AES resin), a styrene/alkyl acrylate ester containing rubbery copolymer/acrylonitrile terpolymer (AAS resin), or a mixture of the AES resin and the AAS resin.
