Fluorine-containing thermoplastic elastomer composition

A wire comprising a sheathing made of a vulcanizate (C wherein vulcanizate (C) is a thermoplastic vulcanizate fluorine-containing composition comprising a continuous thermoplastic fluoropolymer phase and a dispersed vulcanized fluoroelastomer phase, wherein:

• the continuous thermoplastic fluoropolymer phase comprises at least one [polymer (F)], comprising:
• j) from 40 to 60% by moles of recurring units derived from ethylene (E);
• jj) from 60 to 40% by moles of recurring units derived from at least one of chlorotrifluoroethylene (CTFE) and tetrafluoroethylene (TFE);
• and
• jjj) from 0.5 to 10% by moles of recurring units derived from of at least one (per)fluoroalkylvinylether of formula CX2═CX—ORf, wherein each of X, dual to or different from each other, is independently H or F;
• and Rf is a C1-C12 (per)fluoroalkyl group or a C1-C12 (per)fluoro-oxy-alkyl group comprising one or more than one catenary oxygen atoms [monomer (V)], with % by moles being referred to the total moles of recurring units of the polymer (F);
• and
• the dispersed vulcanized fluoroelastomer phase comprises at least one elastomer (A), wherein elastomer (A) is at least one (per)fluoroelastomer.
