PURPOSE: Polyester-based elastomer foam is provided to have a micro cell structure, to have excellent compression plastic deformation property, to have excellent cushion performance and processability, and to have thin layer processability in a blacking process. CONSTITUTION: Polyester-based elastomer foam is formed by foaming a polyester-based elastomer composition. The polyester-based elastomer composition comprises an epoxy-modified polymer and a polyester-based elastomer with the melting point of 180-240 deg. C. The epoxy modified polymer has a weight average molecular weight of 5,000-100,000 and an epoxy equivalent of 100-3000 g/eq. The epoxy modified polymer is at least one polymer selected from epoxy-modified acrylic polymer and epoxy-modified polyethylene. [Reference numerals] (AA) Flow of heat(W/g); (BB) Temperature(°C) |
