More Information
Summary:The invention pertains to a (per)fluoroelastomer composition comprising: -a (per)fluoroelastomer [fluoroelastomer (A)]; and -at least one (per)fluoropolyether additive [polymer (E)] comprising a (per)fluoropolyether chain comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and comprising at least one chain end comprising at least one per(halo)fluorinated aromatic group [group (ArF)], said polymer (E) being comprised in the composition in an amount of 0.5 to 30 phr, with respect to fluoroelastomer (A).
