Abstract
The present application provides a polypropylene composition for preparing a foam. The polypropylene composition comprises (a) a long chain branched polypropylene, and (b) a linear polypropylene, wherein the linear polypropylene has a melt flow rate MFR2 (ISO 1133, 2.16 kg load, 230° C.) of at least 15.0 g/10 min, and wherein the linear polypropylene is present in the polypropylene composition in an amount of at least 30.0 wt. %, based on the total weight of the polypropylene composition. The present application further relates to a foam comprising said polypropylene composition.
