Abstract: The invention relates to an object or object part made from a composition comprising at least one fluoropolymer F, wherein: —the at least one fluoropolymer F comprises vinylidene fluoride units and at least 30 wt. % of units derived from at least one monomer of formula (I): (I) CX1X2═CX3Y, wherein each of X1, X2 and X3 is independently selected from H, Cl, F, Br, I and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partly or fully halogenated and Y is an alkyl group comprising from 1 to 3 carbon atoms which is optionally partly or fully halogenated; —the proportion of the at least one fluoropolymer F in the composition is at least 80 wt. %; and—the viscosity of the composition is at least 1000 Pa·s at a temperature of 230° C. and at a shear rate of 100 s−1.
