POLYESTER SHEET, POLYESTER MOLDED ARTICLE, AND POLYESTER RESIN MASTERBATCH

摘要

A polyester sheet having a surface layer wherein 0.05-2.0% by weight of an ester compound, which is synthesized by using a polyvalent organic acid having 3 or more carboxyl groups and an aliphatic monohydric alcohol having 8 or more carbon atoms, and 0.01-0.5% by weight of inert inorganic particles having an average particle diameter of 2-15 µm are blended into a polyethylene terephthalate polymer.  The polyester sheet has a rational balance between sliding properties and transparency.
