La présente invention concerne une conduite flexible (10) destinée à être immergée dans une étendue d'eau comprenant : - une gaine interne (12) définissant un passage de transport d'un fluide, notamment d'hydrocarbures ; et - au moins une couche d'armures de traction (16, 17) disposée autour de la gaine interne (12). La conduite flexible (10) comporte au moins une gaine polymérique comportant un mélange polymérique comprenant un polymère thermoplastique formant une matrice et au moins une composition de silicone incorporée dans ladite matrice. The present invention relates to a flexible pipe (10) intended to be immersed into a body of water, comprising: - an inner sheath (12) defining a passage for transporting a fluid, in particular hydrocarbons; and - at least one tensile armor layer (16, 17) arranged around the inner sheath (12). The flexible pipe (10) comprises at least one polymeric sheath having a polymeric mixture comprising a thermoplastic polymer forming a matrix, and at least one silicone composition incorporated into said matrix.
