(57) [Abstract] [Objective] A foamed polyester sheet and a method for producing the same. More specifically, the present invention relates to a foamed polyester sheet having uniform fine cells and a high expansion ratio and excellent in high temperature stability, and a method for producing the same. [Structure] (a) 100 parts by weight of a crystalline polyester resin having an intrinsic viscosity of at least 0.6, and (b) a polycarbonate resin having a weight average molecular weight of at least 20,000 10 to 10 100 parts by weight and 0.01) an inorganic nucleating agent selected from the group consisting of glass, mineral materials, and mixtures thereof. A foamed polyester sheet comprising a resin composition containing 5 to 5 parts by weight. |
