摘要: This invention pertains to a thermoplastic fluoropolymer composition comprising: at least one thermoplastic hydrogen-containing fluoropolymer [polymer (A)]; and from 0.1 to 10% by weight of (A) of at least one per(halo)fluoropolymer chosen among tetrafluoroethylene (TFE) copolymers having a dynamic viscosity at a shear rate of 1 rad sec−1 of less than 10 Pa sec at a temperature of 280° C. [polymer (B)]. The addition of a TFE copolymer [polymer (B)] of low melt viscosity advantageously enables improvement of rheological behavior of thermoplastic hydrogen-containing fluoropolymer (A), making possible processing in less severe conditions and yielding final parts with outstanding surface aspect and good homogeneity and coherency.Still objects of the invention are a process for manufacturing said thermoplastic fluoropolymer composition and the articles, such as shaped articles, films, cable sheathing, pipes, flexible pipes, hollow bodies comprising said thermoplastic fluoropolymer composition.
