Abstract

L'invention a pour objet une composition caractérisée en ce qu'elle comprend un mélange d'au moins i) de 75 % à 90 % en masse totale de la composition d'un constituant choisi parmi : - un matériau à base de polypropylène présentant une transmission lumineuse comprise entre 55 et 75 %, - une polyoléfine amorphe, et ii) de 0 à 20 % en masse totale de la composition d'au moins un agent de réduction du coefficient de dilatation thermique, et iii) de 0 à 20 % en masse totale de la composition d'une polyoléfine copolymère élastomère, à la condition que la concentration d'au moins un des constituants ii) et iii) soit différente de 0. L'invention porte également sur des inserts 20 pour pièce 10 de carrosserie de véhicule automobile 40 et sur des procédés de fabrication de pièces 10 de carrosserie de véhicule automobile 40.
