Fluorine-containing elastomeric copolymer and use of the same
Abstract
Abstract 57 A copolymer comprising repeating units derived from tetrafluoroethylene, vinylidene fluoride and hexafluoropropylene in a molar ratio within an area defined on a tetrafluoroethylene, vinylidene fluoride and hexafluoropropylene ternary composition diagram by hexagon with its first vertex A at 34.0 % by weight of tetrafluoroethylene, 8.5 % by weight of vinylidene fluoride and 57.5 % by weight of hexafluoropropylene; its second vertex B at 26.5 % by weight of tetrafluoroethylene, 14.5 % by weight of vinylidene fluoride and 59.0 % by weight of hexafluoropropylene; its third vertex C at 31.0 % by weight of tetrafluoroethylene. 24.0 % by weight of vinylidene fluoride and 45.0 % by weight of hexafluoropropylene; its fourth vertex D at 49.0 % by weight of tetrafluoroethylene, 26.5 % by weight of vinylidene fluoride and 24.5 % by weight of hexafluoropropylene; its fifth vertex E at 49.0 % by weight of tetrafluoroethylene, 11.0 % by weight of vinylidene fluoride and 40.0 % by weight of hexafluoropropylene; and its sixth vertex F at 50.0 % by weight of tetrafluoroethylene, 9.0 % by weight of vinylidene fluoride and 41.0 % by weight of hexafluoropropylene having not only good flexibility, heat resistance and flame retardance but also good insulating performance and moldability.
