Abstract
The invention relates to a moulded article made from a polypropylene composition comprising 48-94.9 mass % of a polypropylene; 5-30 mass % of glass fibers having average length of 1-50 mm; 0.1-2 mass % of oleamide and/or erucamide; and 0-20 mass % of other additives; the article showing a color change of dL<2 in the PSA/Renault scratch tests and a color change of dL<1.5 in the Erichsen scratch test. This article shows an excellent combination of properties, especially a good balance between stiffness and impact resistance, which have excellent surface appearance, and high resistance to surface scratching and abrasion.
