Polypropylene composition for automotive interior applications

摘要

Polypropylene composition comprising (a) a heterophasic propylene copolymer (HECO) comprising (a1) a matrix (M) that is a propylene homopolymer (H-PP) or propylene copolymer (R-PP) and (a2) an elastomeric propylene copolymer (EC) dispersed in said matrix (M), and (b) a mineral filler (F), wherein said heterophasic propylene copolymer (HECO) has (i) a melting temperature determined by scanning calorimetry differential (DSC) in the range of 140 to 155 ° C, (ii) a content of cold xylene soluble (XCS) in the range of 20 to 35% by weight, (iii) a comonomer content of the soluble fraction in cold xylene (XCS) in the range of 18 to 95% by weight, where also the weight ratio between the heterophasic propylene copolymer (HECO) and the mineral filler (F) [(HECO) / (F)] is in the range of 2/1 to less than 4/1.
