POLYESTER RESIN COMPOSITION AND MOLDED PRODUCT USING THE SAME

摘要

PURPOSE: A polyester resin composition is provided to form a flat metal deposition film by direct deposition of metals and to ensure excellent deposition property and heat resistance at high temperature. CONSTITUTION: A polyester resin composition comprises 100 parts by weight of a polyester resin and 0.001-10 parts by weight of perfluoropolyether including a silane functional group. The polyester resin comprises 50-90 weight% of a polybutyleneterephthalate resin and 10-50 weight% of a polyethyleneterephthalate resin. The inherent viscosity(η) of the polybutyleneterephthalate resin is 0.36-1.60 dl/g. and the inherent viscosity(η) of the polyethyleneterephthalate resin is 0.5-1 dl/g.
