Abstract

The present application relates to a polypropylene (PP) composition comprising a) 50.0 to 95.0 wt.-%, based on the total weight of the polypropylene (PP) composition, of a polypropylene (PP) homopolymer being polymerized in the presence of a single-site catalyst and b) 5.0 to 50.0 wt.-%, based on the total weight of the polypropylene (PP) composition, of a mineral filler, to an article comprising the polypropylene (PP) composition as well as the use of the polypropylene (PP) composition for improving the thermo-mechanical properties.
