Mineral-filled polypropylene composition for foaming

A composition comprising:

• (A) from 30 to 85% by weight of one or more propylene-based components being selected from the group consisting of propylene homopolymers, propylene copolymers and heterophasic propylene polymer, such first propylene-based component having a flexural modulus determined in accordance with ISO 178 higher than 800 MPa;
• (B) from 1 to 20% by weight of a heterophasic propylene polymer comprising:
• (B1) from 20 to 90% by weight of a crystalline polypropylene;
• (B2) from 10 to 80% by weight, preferably from 15 to 60% by weight, of a copolymer of ethylene and at least one C3-C10 alpha-olefin, such copolymer containing from 10 to 70% by weight of ethylene, being soluble in xylene at room temperature, and having an intrinsic viscosity in tetrahydronaphtalene at 135° C. from 3.5 dl/g, to 8 dl/g;
• (C) from 1 to 30% by weight, of an ethylene-based plastomer, having a hardness (Shore A, ASTM D-2240) value equal to or lower than 90 points;
• (D) from 5 to 30% by weight of talc.
• (E) from 1 to 10%, by weight of high-density polyethylene (HDPE);
• and
• (F) from 0.1 to 1.5% by weight of an anti-scratch additive.
