(EN) SOFT POLYPROPYLENE COMPOSITION WITH IMPROVED OPTICAL BEHAVIOR
(FR) COMPOSITION DE POLYPROPYLÈNE SOUPLE À COMPORTEMENT OPTIQUE AMÉLIORÉ
Abstract
(EN)
The present invention is directed to a polyolefin composition (C) containing a heterophasic propylene copolymer (TERHECO) and a styrenic thermoplastic (sTPE), wherein the heterophasic propylene copolymer (TERHECO) consists of units derived from propylene, ethylene and 1-hexene. Further the present invention is directed to articles made from the polyolefin composition (C) as well as to the production of sterilized articles.
(FR)
La présente invention concerne une composition de polyoléfine (C) contenant un copolymère de propylène hétérophasique (TERHECO) et un thermoplastique styrénique (sTPE), le copolymère de propylène hétérophasique (TERHECO) étant constitué d'unités dérivées de propylène, d'éthylène et de 1-hexène. La présente invention concerne en outre des articles fabriqués à partir de la composition de polyoléfine (C) ainsi que la production d'articles stérilisés.
