Beschreibung
Zusammenfassung:	The present invention relates to a composition comprising a heterophasic propylene copolymer and an ethylene polymer wherein the ethylene polymer has a density as measured according to ISO 1183-1 (2012), method A of ≥940 kg/m3, the ethylene polymer has a multimodal molecular weight distribution and the ethylene polymer has a strain hardening modulus of ≥5.0 MPa, the strain hardening modulus being measured according to ISO DIS 18488 (2014) using test specimens of 0.30 mm thickness. Such composition has a low surface gloss, while at least one of impact strength, scratch resistance and/or flexural modulus is improved. Such composition may for example be used in automotive interior parts.
