Abstract

See full text

Described herein are polyester polymer compositions including a polyester polymer, a white pigment and hydroxyapatite. It was surprisingly discovered that polyester polymer compositions including hydroxyapatite maintain outstanding retention of reflectance after prolonged exposure to heat and light, while having significantly reduced microblistering and increased mechanical performance relative to analogous polyester polymer compositions including a non-calcium phosphate salt. Accordingly, in some embodiments, the polymer compositions can be desirably incorporated into light emitting diode (“LED”) components.
