POLYESTER RESIN COMPOSITION FOR REFLECTIVE MATERIAL AND REFLECTOR INCLUDING SAME |
摘要 |
The present invention addresses the problem of providing a polyester resin composition which is capable of achieving a reflector that has excellent mechanical strength and heat resistance, maintains high reflectance even when subjected to a heated environment such as an LED manufacturing process or a reflow soldering process, and has small changes in the rate of shrinkage. To solve the problem, a polyester resin composition for a reflective material is provided, the composition comprising 30 to 80 mass% of a polyester resin (A) with a melting point or a glass transition temperature of 250°C or more, 10 to 35 mass% of a glass fiber (B) with a smaller diameter of 3 to 8 μm, 5 to 50 mass% of a white pigment (C), and 0.3 to 1.5 mass% of an olefin polymer (D) that includes 0.2 to 1.8% of a functional group structural unit (provided that a total of (A), (B), (C), and (D) is 100 mass%). |
