Summary:Fluoroelastomeric compositions comprising:A) a fluoroelastomeric matrix;B) a semi-crystalline fluoropolymer, in an amount from higher than 40% to 90% by weight based on the total of A)+B);the fluoroelastomer A) incorporates the fluoropolymer B), the fluoropolymer B) being formed by tetrafluoroethylene (TFE) homopolymers, or by TFE by copolymers with one or more monomers containing at least one unsaturation of ethylene type, the average sizes of the semi-crystalline fluoropolymer particles being from 10 to 100 nm, preferably from 10 to 60 nm.
