Abstract

The invention relates to a composition comprising at least one copolymer comprising polyamide blocks and polyether blocks having a number average molecular weight of from 20 000 to 100 000 g/mol, preferably from 25 000 to 80 000g/mol and wherein the mass ratio of the polyamide blocks relative to the polyether blocks of the copolymer is more than 1; from 0.1 to 6.0 % by weight of expandable microspheres, based on the total weight of the composition; optionally at least one UV stabilizer and/or UV absorber; and optionally at least one additional thermoplastic polymer compatible with the at least one copolymer comprising polyamide blocks and polyether blocks.The invention also relates to a method for preparing such a composition, to an expanded composition obtainable from such a composition and to a method for producing said expanded composition.
