摘要

1/1 summary "molded article, insulating material comprising the same and method for improving the electrical insulation properties of a polyester resin composition". The present invention provides a molded article, which may be suitably used in electrical / electronic components, which exhibits excellent dark resistance and electrical insulation properties, and an insulating material comprising the same. The invention further provides a method for improving the electrical insulation properties of a polyester resin composition. the molded article is obtained by molding a polyester resin composition, comprising from 0.001 to 1.0 part by weight of a sulfonamide compound metal salt or a sulfonimide compound metal salt, relative to 100 mass parts of a polyester resin comprising no less than 50 mass% polybutylene terephthalate.
