Title
(EN) INJECTION MOULDED POLYPROPYLENE ARTICLES
(FR) ARTICLES EN POLYPROPYLÈNE MOULÉS PAR INJECTION
Abstract
(EN) An injection moulded article is disclosed, which is made from a composition comprising: 81-88wt% of a propylene homopolymer (A) having a melt flow rate of between 1 and 2 g/10 min; 12 - 19 wt% of a propylene-ethylene copolymer (B) containing 45 - 65 wt% of ethylene; and 50 -10000 ppm by weight of a nucleating agent, wherein the total ethylene content of the composition is 6 - 10 wt%, and the melt flow rate (MFR) of the composition is 0.7 - 2 g/10 min.
(FR) L'invention porte sur un article moulé par injection, qui est formé à partir d'une composition comprenant : 81-88 % en poids d'un homopolymère de propylène (A) ayant un indice de fluage à l'état fondu compris entre 1 et 2 g/10 min; 12-19 % en poids d'un copolymère de propylène-éthylène (B) contenant 45-65 % en poids d'éthylène; et 50-10000 ppm en poids d'un agent de nucléation, la teneur totale en éthylène de la composition étant de 6-10 % en poids et l'indice de fluage à l'état fondu (MFR) de la composition étant de 0,7-2 g/10 min.
