A crosslinkable fluororubber composition comprising (A)na polymer of the formula: Z-(Rf-Q) n -Rf-Z wherein n is anninteger of at least 1, Rf is a divalent perfluoroalkylene ornperfluorooxyalkylene radical, Q is a divalent organicnradical, and Z is a monovalent organic radical, having anviscosity of at least 1,000 Pa·s at 25°C, (B) a reinforcingnfiller, and (C) a peroxide crosslinking agent is effectivelynroll milled and experiences minimal changes of viscositynafter milling. Molded parts can be produced on a mass scale. |
