Silicone Materials for LEDs

About Shin-Etsu LED Silicone MaterialsApplication examplesProduct lineupSilicone materials for LED-Display & Lighting ModulesReference material

Silicones for LED applications are driving the evolution of LEDs.

LEDs (light-emitting diodes) consume less energy, are long-lasting, and are eco-friendly. As they have become higher in brightness, they have come to be used in a wide variety of applications. LEDs used for illumination and TV backlights in particular must provide long-lasting reliability, which makes silicone a vital material for the manufacture of such LEDs.

Silicone is used as an encapsulant and die-bonding adhesive, and manufacturers are working toward using it as a reflector material. Silicone is driving the evolution of LEDs.
