    Abstract: A polyethylene-polypropylene composition obtainable by blending a) 80 to 97 wt.-% of a blend (A) comprising A-1) polypropylene and A-2) polyethylene, wherein the ratio of polypropylene to polyethylene is from 3:7 to 13:7, and wherein blend (A) is a recycled material, which is recovered from a waste plastic material derived from post-consumer and/or post-industrial waste; and b) 3 to 20 wt.-% of a compatibilizer (B) being a heterophasic random copolymer comprising a random polypropylene copolymer matrix phase and an elastomer phase dispersed therein, whereby the heterophasic random copolymer has—a xylene insolubles content (XCI) of from 65 to 88 wt.-% (ISO 16152, led, 25° C.), and—a xylene soluble content XCS of 12 to 35 wt.-% (ISO 16152, led, 25° C.), the XCS fraction having an intrinsic viscosity (measured in decalin according to DIN ISO 1628/1 at 135° C.) of 1.2 dl/g to less than 3.0 dl/g, and—a flexural modulus of from 300 to 600 MPa (ISO 178, measured on injection moulded specimens, 23° C.); whereby the ratio of MFR2 (blend (A))/MFR2 (compatibilizer (B)) (ISO1133, 2.16 kg load at 230° C.), is in the range of 0.5 to 1.5.

    Abstract: A polypropylene-polyethylene composition obtainable by blending a) 80 to 97 wt.-% of a blend (A) comprising A-1) polypropylene and A-2) polyethylene, wherein the weight ratio of polypropylene to polyethylene is from 9:1 to 13:7, and wherein blend (A) is a recycled material, which is recovered from waste plastic derived from post-consumer and/or post-industrial waste; and b) 3 to 20 wt.-% of a compatibilizer (B) being a heterophasic random copolymer comprising a random polypropylene copolymer matrix phase and an elastomer phase dispersed therein, whereby the heterophasic random copolymer has—a xylene insoluble content XCI of 65 to 88 wt.-% (ISO 16152, led, 25° C.), —a xylene soluble content XCS of 12 to 35 wt.-% (ISO 16152, led, 25° C.), the XCS fraction having an intrinsic viscosity (measured in decalin according to DIN ISO 1628/1 at 135° C.) of 1.2 dl/g to less than 3.0 dl/g, and—a flexural modulus of from 300 to 600 MPa (ISO 178, measured on injection moulded specimens, 23° C.); and wherein, the ratio of MFR2 (blend (A))/MFR2 (compatibilizer(B)) (ISO1133, 2.16 kg load), is in the range of from 1.5 to 3.5 g/10 min.
