LED applications

Heat resistance is required for materials for high-visibility LEDs which consume less power due to the high temperatures involved in the package manufacturing process. Furthermore, GENESTAR™ functions as a heat-resistant resin because when reflectors are used there is a requirement of discoloration resistance in the presence of heat and light. It is utilized in reflectors of LED light sources that are often found in LED lighting, LCD televisions, smartphones, and tablet.

Initial brightness / long-term heat resistance / light fastness

GENESTAR™ PA9T LED high brightness grades have high heat resistance,
GENESTAR™ PA9C has high UV resistance.
