Super phosphorescent additives for high-quality illumination at low additive-loading levels

摘要

A new super-phosphorescent additive represents a breakthrough in the use of phosphorescence for plastic products. The new additive provides a substantially longer glow time than conventional zinc sulfide phosphorescent additives. Additionally, it, can be compounded at far lower loading levels, which facilitates compounding and processing, and makes the new additive more compatible with other fillers than zinc sulfide. This paper discusses attributes, applications, and performance characteristics of this novel product, and compares it to commonly used phosphorescent compounds.
