A low-density, thermoplastic foam comprising: (a) thermoplastic polymer cells comprising cell walls forming closed cells, wherein said thermoplastic polymer comprises ethylene furanoate moieties and optionally ethylene terephthalate moieties, wherein said polymer comprises from about 1 mole% to about 100 mole% of ethylene furanoate moieties and optionally at least about 1 mole% ethylene terephthalate moieties; and (b) one or more HFOs having three or four carbon atoms and/or one or more HFCOs having three or four carbon atoms contained in the closed cells. Mousse thermoplastique basse densité comprenant : (a) des alvéoles polymères thermoplastiques comprenant des parois d'alvéoles formant des alvéoles fermées, ledit polymère thermoplastique comprenant des fragments furanoate d'éthylène et éventuellement des fragments téréphtalate d'éthylène, ledit polymère comprenant d'environ 1 % en moles à environ 100 % en moles de fragments furanoate d'éthylène et éventuellement au moins environ 1 % en moles de fragments téréphtalate d'éthylène ; et (b) un ou plusieurs HFO ayant trois ou quatre atomes de carbone et/ou un ou plusieurs HFCO ayant trois ou quatre atomes de carbone, contenus dans les alvéoles fermées.
