PURPOSE:To obtain a formed rubber article having improved compression set, by applying a specific dose of radiation to a rubber composition containing a TFE-P fluororubber which is a copolymer of tetrafluoroethylene and PP as a base after the primary or secondary vulcanization. CONSTITUTION:A rubber composition containing a TFE-P fluororubber (a copolymer of tetrafluoroethylene and PP) as a base is irradiated with radiation of preferably 5-10 Mrad after the primary or secondary vulcanization, to obtain the objective formed article. |
