Abstract
(EN)
A polypropylene composition comprising a random propylene copolymer, a high melt strength polypropylene having a branching index g' of 0.9 or less, a polypropylene having a MFR2 (230°C) of at least 400.0 g/10min and a clarifier, wherein the polypropylene composition has a MFR2 (230°C) of at least 2.0 g/10min.
(FR)
L'invention concerne une composition de polypropylène qui comporte un copolymère statistique de propylène, un polypropylène à résistance élevée à la fusion ayant un indice de ramification g' de 0,9 ou moins, un polypropylène ayant un indice de fluidité à chaud (MFR2) (à 230°C) d'au moins 400,0 g/10 mn et un agent clarifiant, ladite composition de polypropylène ayant un indice de fluidité à chaud (MFR2) (à 230°C) d'au moins 2,0 g/10 mn.
