Abstract: The present invention is directed to articles comprising a heterophasic polypropylene composition. The articles exhibit a combination of high stiffness, good dimensional stability, low shrinkage and reduced warpage properties and fast cycle times. Such articles are suitable in the rigid packaging area. The articles comprise a polypropylene composition comprising a heterophasic propylene copolymer which comprises a) a matrix phase (A) comprising at least one propylene homopolymer and/or a propylene copolymer, and b) a disperse phase (B) comprising a propylene copolymer rubber dispersed in the matrix phase (A), wherein the propylene copolymer rubber of the disperse phase (B) has a comonomer content of 30 to 55 wt. %, wherein the weight ratio of the matrix phase (A) and the disperse phase (B) is from 20:80 to 80:20; and the polypropylene composition has (i) a melt flow rate MFR2 of 1 g/10 min to 500 g/10 min, determined according to ISO 1133 (230° C., 2.16 kg load); and the article has (ii) a half-time of crystallisation t1/2 of 1 to 25 msec, measured at 80° C. by fast scanning calorimeter. The invention further relates to a process for preparing such a heterophasic polypropylene composition and its use for e.g. molded articles, in particular injection molded articles such as thin-walled containers.
