Abstract: The present invention relates to a polypropylene composition comprising —10 to 50 wt. % of recycled polypropylene (R-PP) and/or linear polypropylene (L-PP); —40 to 89.95 wt. % of a high melt strength polypropylene (HMS-PP) having an F30 melt strength of more than 25.0 cN and a v30 melt extensibility of more than 205 mm/s, wherein the F30 melt strength and the v30 melt extensibility are determined according to ISO 16790:2005; and —0.05 to 10 wt. % of a nucleating agent (NA); a foamed sheet formed from the polypropylene composition; an article comprising the foamed sheet and a process comprising the step of forming the polypropylene composition. Furthermore, the invention is further directed to the usage of the polypropylene composition for the formation of foamed sheets.

Abstract: The present invention relates to a foamed sheet consisting of a polypropylene composition comprising at least 85 wt. %, e.g. from 85 to 99.5 wt.-%, of a high melt strength polypropylene (HMS-PP) and 0.5 to 15 wt. % of a nucleating agent (NA), wherein the foamed sheet has a thickness of below 0.5 mm or a thickness of 2.0 mm or more. The present invention further relates to a foamed material consisting of a polypropylene composition as well as the use of a polypropylene composition comprising at least 85 wt. %, e.g. from 85 to 99.5 wt.-%, of a high melt strength polypropylene (HMS-PP) and 0.5 to 15 wt. % of a nucleating agent (NA) for producing foamed material.
