Abstract
The present invention relates to a propylene copolymer composition comprising (A) from 50.0 to 95.0 wt %, based on the total amount of the propylene copolymer composition, of a heterophasic propylene copolymer having a matrix phase and an elastomeric phase dispersed in said matrix phase, wherein the matrix phase is a propylene random copolymer, the heterophasic propylene copolymer further having a melt flow rate MFR2 of 0.2 to 12.0 g/10 min, determined according to ISO 1133 at a temperature of 230° C. and a load of 2.16 kg, and a xylene cold solubles (XCS) fraction in the range of from 20.0 to 50.0 wt % based on the total amount of the heterophasic propylene copolymer (A), determined according to ISO 16152 at a temperature of 25° C., and (B) from 5.0 to 25.0 wt %, based on the total amount of the propylene copolymer composition, of a propylene based plastomer having a density in the range of from 845 to 870 kg/m, determined according to ASTM D 1505 on compression moulded test specimens and a melt flow rate MFR2 of 1.0 to 30.0 g/10 min, determined according to ASTM D1238 at a temperature of 230° C. and a load of 2.16 kg, wherein the propylene copolymer composition has a tensile modulus of below 300 MPa, determined according to ISO 527-2, measured on injection moulded test specimens, and follows the following inequation: tensile modulus [MPa]<375 MPa−6×amount of (B) [MPa×wt %/wt %], an article comprising said propylene copolymer composition and the use of said propylene copolymer composition in a single ply roofing membrane.
