An ionically crosslinkable fluoroelastomer composition comprising: (a) at least one fluoroelastomer [polymer (F)]; (b) at least one ionically crosslinking system comprising at least one accelerator and at least one curing agent; (c) from 0.5 to 20 weight parts, per hundred parts of fluoroelastomer [polymer (F)], of at least one polar compound having boiling point of 150° C. or less, selected among: alcohols having formula: RH—OH wherein RH is a C1-12 hydrocarbon group, aliphatic or aromatic, substituted or unsubstituted, linear or branched; aldehydes having formula: wherein R′H is a C1-12 hydrocarbon group, aliphatic or aromatic, substituted or unsubstituted, linear or branched; ketones having formula: wherein R″H groups, equal or different from each other, are C1-6 hydrocarbon groups, aliphatic or aromatic, substituted or unsubstituted, linear or branched; esters having formula: wherein R′″H groups, equal or different from each other, are C1-6 hydrocarbon groups, aliphatic or aromatic, substituted or unsubstituted, linear or branched.
