FIELD: chemistry.

SUBSTANCE: invention relates to an article for decorating the interior of a car. The article is made from a composition which contains at least 50 wt % polypropylene composition with melt flow rate MFR₂ (230°C) from 2.0 to 80.0 g/10 min. The polypropylene composition contains at least 25 wt % heterophase polypropylene (H-PP1), at least 25 wt % heterophase polypropylene (H-PP2), at least 10000 to 550000 ppm inosilicate and 1000 to 5000 ppm phenol antioxidants. Each of said heterophase polypropylenes contains a polypropylene matrix which is a propylene homopolymer, and an elastomeric copolymer containing links that are derivatives of propylene and ethylene and/or alpha-olefins C4-C20. The weight content in the heterophase polypropylene (H-PP1) of substances that are soluble in cold xylene, measured according to ISO 6427, ranges from 15.0 to 40.0%, and from 5.0 to 20.0% in the heterophase polypropylene (H-PP2).

EFFECT: invention improves the result of odour evaluation based on sensory perception, and also considerably reduces the emission of all volatile compounds from the product, particularly 2-methyl-1-propene, without losing mechanical properties of the article, such as tensile modulus and/or flexural modulus.
