Title: FOAMED SHEET OF THERMOPLASTIC POLYESTER RESIN AND FOAMED CONTAINER OF THERMOPLASTIC POLYESTER RESIN
Abstract:
A foamed sheet of a thermoplastic polyester resin, characterized by: comprising a thermoplastic polyester resin and one or more crystallization accelerators selected from among inorganic crystallization accelerators and organic crystallization accelerators; and giving, when examined with a heat-flux differential scanning calorimetry (DSC) device by conducting second heating at a heating rate of 100 °C/min from 30°C to 110°C and keeping the temperature at 110°C for 30 minutes, a DSC curve in which the time period (crystallization time) from the time when the second heating started to the time corresponding to the top A of an exothermic peak observed latest is 14 minutes or less.
