Beschreibung
Zusammenfassung:	The invention relates to a foamable polymer composition comprising a polyolefin polymer which polyolefin polymer does not bear silane moieties and comprises 20 to 99.99 wt.% linear low density polyethylene, and a blowing agent in an amount of 0.01 to 3 wt.% based on the total foamable polymer composition, wherein the blowing agent consists of citric acid and/or derivatives of citric acid or mixtures thereof. Further the invention relates to a foamable polymer composition comprising a polyolefin polymer, and a blowing agent in an amount of 0.01 to 3 wt.% based on the total foamable polymer composition, wherein the blowing agent consists of expandable polymeric microspheres, and the composition does not comprise fluororesin.Further the invention relates to a foamed polymer composition obtained by foaming this foamable polymer composition. Further the invention relates to the use of the foamable composition or the foamed polymer composition for a layer of a cable and a cable comprising at least one layer which comprises the foamable polymer composition or the foamed polymer composition.
