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.

Abstract: A compound is prepared, suitable for forming fluoroelastomers, having the unique features of a low glass transition temperature and desirable physical properties. The compound generally comprises an elastomeric copolymer, a curable component, and at least one mineral filler. The elastomeric copolymer includes interpolymerized monomeric units derived from vinylidene fluoride. Upon vulcanization the resulting elastomeric compound has desirable physical characteristics as indicated by the tensile strength, elongation and the retraction at lower temperatures (TR-10).
