LEATHER-LIKE THERMOPLASTIC POLYESTER SERIES RESIN SHEET AND PROCESS FOR PRODUCTION OF THE SAME

摘要

A leather-like thermoplastic polyester series resin sheet is disclosed, comprising a uniformly and finely formed sheet comprising a thermoplastic polyester series resin, wherein said foamed sheet has cells having a diameter of substantially not longer than 1 mm, the cell walls thereof have a thickness of substantially not thicker than 100 mu m, and the cell wall constructing each cell extends with irregular bending so as to make a flexibility of not more than 20,000 mg in the Gurley flexibility test. A process for production of the leather-like thermoplastic polyester series resin sheet is also disclosed.
