HIGHLY RIGID AND HEAT RESISTANT POLYESTER MULTILAYER SHEET, AND MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a heat resistant polyester multilayer sheet having high rigidity even at the time of high temperature and surface gloss, and a molding. SOLUTION: The highly rigid and heat resistant polyester multilayer sheet comprises a surface layer containing 92 to 99 wt.% of polyethylene terephthalate resin having an intrinsic viscosity of 0.6 deciliter/g or more and 1 to 8 wt.% of polyolefin resin, and a base layer containing 35 to 83 wt.% of polyethylene terephthalate resin having an intrinsic viscosity of 0.6 deciliter/g or more, 2 to 25 wt.% of polyolefin resin and 15 to 50 wt.% of inorganic compound.
