Abstract: The invention relates to a non-cross-linked copolymer foam with polyamide blocks and polyether blocks, wherein: the polyamide blocks of the copolymer have an average molar mass of from 200 to 1,500 g/mol; the polyether blocks of the copolymer have an average molar mass of from 800 to 2,500 g/mol; and the weight ratio of the polyamide blocks to the polyether blocks of the copolymer is from 0.1 to 0.9. The invention also relates to a method for manufacturing said foam and items manufactured from said foam.

Abstract: The present invention relates to a non-crosslinked block copolymer foam composition, characterised in that it is in the form of a polymer matrix comprising closed cells containing gas, said matrix comprising:



from 90 to 99.9% by weight of said block copolymer; and
from 0.01 to 10% by weight of metal carbonate,


for the total weight of the foam composition.


The present invention also relates to a foamable composition and a method for manufacturing said foam, as well as the use of the foam in sports shoe soles, balloons or balls, gloves, personal protection equipment, rail soles, automobile parts, construction parts, electrical and electronic equipment parts, audio equipment, sound- and/or heat-proofing, and parts used to damp vibrations.
