POLYAMIDE COMPOSITION FOR REFLECTING PLATE, REFLECTING PLATE, LIGHT EMISSION DEVICE HAVING THE REFLECTING PLATE, AND ILLUMINATION DEVICE AND IMAGE DISPLAY HAVING THE LIGHT EMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polyamide composition for a reflecting plate, which has high heat resistance and good dynamic properties when being molded, is excellent in tight adhesion with a sealing member for LED packaging, and can hold a high reflectance even after receiving heat and light assumed in a manufacture step and use environment of LED packaging.

SOLUTION: The polyamide composition for a reflecting plate contains ≥30 mass% of a polyamide (A) having a melting point of ≥280°C and ≥25 mass% of titanium oxide (B), wherein the total content of the polyamide (A) and the titanium oxide (B) is ≥75 mass%, and ≥50 mass% of the polyamide (A) is used as a solid having a particle diameter in the range of ≤1 mm.
