Abstract
The present invention relates to a propylene polymer composition comprising a long chain branched propylene polymer, wherein said propylene polymer composition has a) a melt flow rate MFR(230° C., 2.16 kg) of 0.8 to 6.0 g/10 min b) a xylene hot insolubles (XHU) fraction in an amount of not more than 0.80 wt %, based on the total weight amount of the propylene polymer composition, c) a melting temperature Tm of at least 160.0° C., d) a F30 melt strength of from 5.0 to less than 30.0 cN, and e) a heat distortion temperature (HDT) of at least 108° C., a process for producing said propylene polymer composition by reactive modification of a propylene polymer in the presence of a peroxide, an article comprising said propylene polymer composition and the use of said propylene polymer composition for producing an article.
