Filled polypropylene (PP) compositions with improved thermo-mechanical properties

A polypropylene (PP) composition consisting of:

• a) 50.0 to 95.0 wt. %, based on the total weight of the polypropylene (PP) composition, of a polypropylene (PP) homopolymer that is prepared in the presence of a single-site catalyst and having:
• i) a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 1 to 200 g/10 min,
• ii) a melting temperature (Tm) measured by differential scanning calorimetry (DSC) of ≥153° C., and
• iii) a molecular weight distribution Mw/Mn measured according to ISO 16014 in the range of 3.6 to 4.5,
• b) 5.0 to 50.0 wt. %, based on the total weight of the polypropylene (PP) composition, of a mineral filler,
• c) up to 2.0 wt. %, based on the total weight of the polypropylene composition, of one or more additives selected from the group consisting of acid scavenger, colorants, pigments, anti-scratch agents, dispersing agents, UV stabilizers, antistatic agents, demoulding agents and carriers,
• d) optionally from 0.002 to 1.5 wt. %, based on the total weight of the polypropylene composition, of a nucleating agent comprising a phosphate-based α-nucleating agent, and
• e) optionally further polymer(s) different to the polypropylene (PP) homopolymer in an amount not exceeding in total 2.0 wt. %, based on the total weight of the polypropylene (PP) composition, wherein the further polymer(s) different to the polypropylene homopolymer is/are carrier polymer(s) for additives.
