Abstract: Described herein is method of making elongated fluoroelastomeric articles using a millable composition comprising (a) a random fluorinated polymer, the random fluorinated polymer comprising repeating divalent monomeric units derived from TFE, HFP and VDF and further comprising 0.1 to 1% by weight iodine, wherein the random fluorinated polymer has an MFI greater than 5 g/10 min at 265° C. and 5 kg; (b) a filler, and (c) a peroxide, wherein the millable composition has a melting point less than 125° C. Such compositions can be used to make elongated articles such as stators.
