| 摘要 |
The present invention provides a polyester foamed sheet composed of a resin composition comprising 50 to 100 weight% of a polyalkylene terephthalate, wherein the resin composition has an isothermal crystallization peak time of 5 to 60 seconds at any temperature of 100 to 150°C, and wherein the sheet has (A) an apparent density of 0.05 to 1.25 g/cm 3 and (B) a temperature at which an exothermic peak derived from crystallization is observed of 0 to 150°C when thermal analysis is performed using an input compensation type differential scanning calorimeter. |
