Beschreibung
Zusammenfassung:	PURPOSE: Provided are an uncrosslinked foaming polyester-based thermoplastic elastomer composition and an uncrosslinked foaming polyester-based thermoplastic elastomer foam obtained from the composition which has a cell of fine average size and uniform distribution, is excellent in impact resistance, sealing property and vibration isolation and can be recycled. CONSTITUTION: The uncrosslinked foaming polyester-based thermoplastic elastomer composition comprises 60-100 parts by weight of an uncrosslinked foaming polyester-based thermoplastic elastomer; 1-10 parts by weight of a foaming agent; and 1-10 parts by weight of a viscosity controller. Preferably the composition comprises further at least one thermoplastic resin selected from the group consisting of ethylene-vinyl acetate, low density polyethylene, linear low density polyethylene, polypropylene, metallocene polyethylene, poly(vinyl alcohol), polystyrene, acrylonitrile-butadiene-styrene copolymer, poly(ethylene terephthalate) and poly(butylene terephthalate), in an amount of 5-40 parts by weight.
