Abstract

L'invention concerne une composition de polyoléfine (I) comprenant : (A) de 65 à 95% en poids d'une composition de polypropylène ayant un MFR(A) de 0,2 à 1,2 g/10 min comprenant : de 15 à 40% en poids d'une fraction polymère (a) comprenant un propylène, la fraction polymère (a) ayant une solubilité dans le xylène à 25°C ≤ 10,0% en poids ; et de 60 à 85% en poids d'une fraction polymère (b) comprenant un copolymère d'éthylène avec un comonomère choisi parmi le propylène et/ou une alpha-oléfine en CH2=CHR, le copolymère contenant de l'éthylène en une quantité ≤ 40% en poids, la fraction polymère (b) ayant une solubilité dans le xylène à 25°C ≥ 60% en poids, et (B) de 5 à 35% en poids d'un polymère d'éthylène recyclé ayant une densité ≤ 0,93 g/cm3 et un MFR(B) de 0,1 à 10,0 g/10 min.
