Beschreibung
Zusammenfassung:	The invention is related to a glass fibre reinforced polypropylene composition with superior balance of strength/stiffness and the strain at break. The composition comprises a heterophasic polypropylene copolymer and a propylene polymer with a specified melt flow rate together with a polar modified polypropylene as an adhesion promoter. It is further related to articles comprising the glass fibre reinforced polypropylene composition. L'invention concerne une composition renforcée de fibres présentant un équilibre supérieur entre résistance/dureté et contrainte à la rupture. Elle se rapporte en outre à des articles comportant cette composition renforcée de fibres.
