Abstract
The present invention is directed to a polypropylene composition (C) comprising a heterophasic propylene copolymer (HECO), comprising a matrix being a propylene polymer (PP1), an elastomeric propylene copolymer (EPR) being dispersed in said matrix and a nucleating agent (NU). The polypropylene composition (C) further comprises polymeric fibers (PE). The present invention is also directed to a foamed article comprising the polypropylene composition (C) and the use of polymeric fibers (PE) as an impact modifier for a heterophasic propylene copolymer (HECO).
