Polyester resin composition having good reflectance, heat resistance, yellowing resistance and humidity resistance

摘要

A polyester resin composition comprises (A) 100 parts by weight of polyester resin with a melting point greater than 200 °C and including repeat units of Formula 1; (B) 0.1 to 80 parts by weight of white pigment; and (C) 0.01 to 80 parts by weight of filler. The polyester resin composition of the present invention does not exhibit deteriorated reflectance and impact strength and also has good heat resistance, non-yellowing property and humidity resistance and can be used in a light emitting diode (LED) reflector.
