1. A fluoropolymer [polymer (F)] comprising:
from 60% to 80% by moles of recurring units derived from tetrafluoroethylene (TFE),
from 15% to 35% by moles of recurring units derived from vinylidene fluoride (VDF), and
from 1% to 5% by moles of recurring units derived from perfluoropropylvinylether of formula CF2═CF—O—C3F7,
wherein the molar amounts of said recurring units are relative to the total moles of recurring units in said polymer (F).
