Polymer compositions for the production of cables and flexible pipelines as well as articles based on these compositions

摘要

Polymer compositions based on fluoropolymers intended especially for the manufacture of electrical cables and hoses (flexible pipes), comprising, by weight, (A) from 25 to 75% of a PVDF homopolymer; (B) from 25 to 75% of a thermoplastic copolymer of VF2 and of at least one other fluorine-containing monomer, having a content of this other monomer of from 5 to 25%. This other fluorine-containing comonomer may especially be CTFE (chlorotrifluoroethylene), HFP (hexafluoropropylene) or TrFE (trifluoroethylene). The articles produced at the outset from these compositions possess good cold mechanical properties.
