  • Fluoroelastomer composition and molded article thereof
    Patent number: 11492480
    Abstract: The invention provides a fluoroelastomer composition that can be crosslinked at an industrially sufficient rate without the use of a graphene having specific surface properties and can provide a fluoroelastomer molded article having higher tensile strength and better abrasion resistance than conventional fluoroelastomer molded articles even though having a similar tensile modulus to conventional fluoroelastomer molded articles. The fluoroelastomer composition contains a fluoroelastomer that contains a crosslinkable group-containing monomer unit and an elongated sheet-shaped graphene. The graphene exhibits a ratio (L/W) of a maximum length (L) and a width (W) of 2 to 105, and the graphene exhibits a ratio (L/T) of the maximum length (L) and a thickness (T) of 1×101 to 1×107.
    Type: Grant
    Filed: June 4, 2018
    Date of Patent: November 8, 2022
    Assignees: TOKYO INSTITUTE OF TECHNOLOGY, DAIKIN INDUSTRIES, LTD.
    Inventors: Masatoshi Shioya, Kenta Kubo, Shinya Maruta, Tsuyoshi Noguchi
