Abstract: The present invention relates to a new polypropylene composition for molded articles, such as finished parts for the automotive industry. A composition comprising: (A) from 40 to 85% by weight of a first propylene-based component being selected from propylene homopolymers, propylene copolymers and heterophasic propylene polymer, such first propylene-based component having a flexural modulus higher than 800 MPa; (B) from 5 to 20% by weight of a second propylene-based component being a heterophasic propylene polymer comprising: (B1) from 20 to 90% by weight of a crystalline polypropylene, and (B2) from 10 to 80% 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. of higher than 3.5 dl/g; and (C) from 10 to 40% by weight of glass fibers.
