Polymer compositions intended for the manufacture of cables and flexible pipes and articles based on these compositions

摘要

Polymer compositions based on fluoropolymers intended especially for the manufacture of electrical cables and of flexible pipes, comprising, by weight,PP(A) from 25 to 75% of PVDF homopolymer; PP(B) from 25 to 75% of a thermoplastic copolymer of VF.sub.2 and of at least one other fluoromonomer, exhibiting a content of 5 to 25% of this other monomer. This other fluorocomonomer may be in particular CTFE (chlorotrifluoroethylene), HFP (hexafluoropropylene) or TrFE (trifluoroethylene). Articles produced from these compositions have good mechanical properties at low temperature.
