According to the present invention, Repeating units derived from tetrafluoroethylene (TFE); And Contains a repeating unit derived from perfluoromethylvinylether (MVE) and has a Mooney viscosity (ML2 + 9) at 121 ° C. of 25 to 140 MU, as measured according to ASTM D1646 standard, of TFE and MVE. Peroxide cured perfluoroelastomers comprising the MVE repeat units in an amount of 26 to 33 mole percent, based on the total moles, and methods for preparing the same, and articles obtainable therefrom. |
