Abstract: A process for reducing the volatile and semi-volatile organic content (VOC and FOG values) of a heterophasic polypropylene composition, the heterophasic polypropylene composition comprising (i) at least 15 wt.-% of at least a first heterophasic polypropylene; (ii) less than 15 wt.-% of at least one elastomeric polyolefin, (iii) at least one filler; (iv) optionally polyethylene; and (v) optionally further polyolefins to below 100 μg/g (VOC, VDA 278 October 2011) and below 390 μg/g (FOG, VDA 278 October 2011), the process involving aerating the first heterophasic polypropylene and each further polyolefin component that is present in an amount of at least 15 wt.-% relative to the total weight of the heterophasic polypropylene composition, before extruding these aerated components with the at least one elastomeric polyolefin and the at least one filler and the optional polyethylene and/or optional further polyolefin(s).
