The present invention relates to a fluorinated polymer comprising per 100 parts by weight of composition: optionally from 1 to 6 parts, preferably from 2 to 5 parts, of at least one plasticizer compatible with the fluorinated polymer; from 4 to 10 parts, preferably from 5 to 8 parts of particles of a core-shell type impact modifier which comprises at least one inner layer of a soft polymer having a Tg <-25 ° C, advantageously <-40 ° C and preferably <-60 ° C and an acrylic bark; the complement of 100 parts of at least one homopolymer or copolymer of VDF; characterized in that the impact modifier particles have an interparticular distance DI of at most 150 nm, preferably at most 100 nm. This composition may be used for the manufacture of: pipes intended to convey a fluid under pressure and / or corrosive; or hollow bodies for storing a fluid under pressure and / or corrosive; or a monolayer or multilayer film; or to manufacture a sealing sheath of an offshore pipe. |
