Abstract
The present invention concerns a foamable polymer composition and a foamed polymer composition obtained by foaming this foamable polymer composition. The invention is also concerned with a cable comprising at least one layer which comprises the foamable polymer composition or the foamed polymer composition. The invention further provides a process for producing a foamed polymer composition.
Claims16
Foamable polymer composition comprising
- (A) a first polyolefin polymer,
- (B) a second polyolefin polymer having an MFR2 (2.16 kg;
- 190° C.) of 2 to 15 g/10 min measured according to ISO 1133-1, and
- (C) a mineral nucleating agent in an amount of 0.5 to 6 wt. % based on the total foamable polymer composition,
- wherein the first polyolefin polymer (A) has a higher density than the second polyolefin polymer (B).
