(57) [Summary] [Structure] (A) Fluorine rubber obtained by copolymerizing vinylidene fluoride (VdF) and hexafluoropropylene (HFP), or obtained by copolymerizing VdF, HFP and tetrafluoroethylene Fluororubber, (B) organic quaternary phosphonium salt, (C) polyhydroxy compound (D) fluororubber composition comprising metal oxide and / or metal hydroxide, and fluororubber vulcanization using the fluororubber composition Molded article manufacturing method. [Effect] It is possible to obtain a fluororubber composition free from molding defects when the fluororubber is molded by polyol vulcanization using a mold. |
