Title
(EN) PROPYLENE POLYMER COMPOSITION
(FR) COMPOSITION POLYMERE DE PROPYLENE
Abstract
(EN)
Disclosed are fabricate automotive articles comprising a propylene polymer composition comprising a polypropylene, an interpolymer prepared from a metallocene catalyst, and optionally a filler. Said fabricated automotive articles have a good balance of stiffness and toughness and demonstrate improved scratch and mar resistance.
(FR)
L'invention concerne des articles automobiles préfabriqués comprenant une composition polymère de propylène renfermant un polypropylène, un interpolymère obtenu à partir d'un catalyseur métallocène, et éventuellement une charge. Lesdits articles automobiles préfabriqués présentent un bon équilibre en termes de rigidité et de ténacité et une résistance à la rayure et aux éraflures améliorée.
