  • Chlorotrifluoroethylene copolymer
    Patent number: 9266986
    Abstract: The present invention provides a chlorotrifluoroethylene copolymer endowed with stress cracking resistance, chemical resistance and thermal stability. The present invention is a chlorotrifluoroethylene copolymer constituted of chlorotrifluoroethylene unit, tetrafluoroethylene unit and a monomer [A] unit derived from a monomer [A] copolymerizable with chlorotrifluoroethylene and tetrafluoroethylene, wherein the sum of chlorotrifluoroethylene unit and the tetrafluoroethylene unit amounts to 90 to 99.9 mole percent and the monomer [A] unit amounts to 0.1 to 10 mole percent.
    Type: Grant
    Filed: April 13, 2005
    Date of Patent: February 23, 2016
    Assignee: DAIKIN INDUSTRIES, LTD.
    Inventors: Takeshi Shimono, Takahisa Aoyama, Hiroshi Torimae, Takahiro Kitahara
  • Fluid transfer member
    Patent number: 8747973
    Abstract: The present invention provides a fluid transfer member having thermal stability on the occasion of molding, stress cracking resistance and low liquid chemical permeability at the same time. The present invention is a fluid transfer member which is composed by a laminate containing a layer [P] comprising a fluoropolymer and/or a fluorine-free organic material and a layer [Q] comprising a chlorotrifluoroethylene copolymer.
