preparation example Construction

[0237] As regards the preparation of the polypropylene homopolymer (PP-H1 ) reference is made to the above description provided for the polypropylene matrix (M) of the heterophasic propylene copolymer (HPP), ie the polypropylene homopolymer (PP-H2).

[0238] Mineral filler (F)

[0239] In addition to the polymer component, the polymer composition according to the present invention is also contained in the range of 20.0 to 40.0 wt%, and preferably in the range of 25.0 to 35.0 wt%, based on the total weight of the polymer composition mineral filler (F). Another requirement of the present invention is that the mineral filler (F) is selected from the group consisting of talc, wollastonite, kaolin and mica.

[0240] In one embodiment of the invention, the mineral filler (F) is talc.

[0241] The average particle size d50 of the mineral filler (F) is preferably in the range of 0.5-20.0 μm, more preferably in the range of 0.5-15.0 μm, still more preferably in the range of 0.75-10.0...

Abstract

The present invention is directed to a polypropylene composition (C), an article comprising the polypropylene composition (C) as well as the use of the polypropylene composition (C) to reduce paintability failure of a molded article.

Description

Technical field [0001] The present invention relates to a polypropylene composition (C), articles comprising said polypropylene composition (C) and the use of said polypropylene composition (C) for reducing paintability failures of molded articles. Background technique [0002] Polypropylene is the material of choice in many applications when it can be tailored to meet the requirements of a specific use. For example, heterophasic polypropylene is widely used in the automotive industry (eg, bumper applications) when it combines good stiffness with reasonable impact strength properties. Heterogeneous polypropylene consists of a polypropylene matrix with an amorphous phase dispersed within the polypropylene matrix. The amorphous phase includes: a plastomer, such as linear low density polyethylene (LLDPE); or a propylene copolymer rubber, such as ethylene propylene rubber (EPR) or ethylene propylene diene monomer polymer (EPDM). In the case of propylene copolymer rubber, the h...
