High-purity, high-transparency silicone material for LED
LPS series
Shin-Etsu Chemical's LPS series are silicone resin for various LEDs (white LEDs, ultraviolet LEDs, blue LEDs) encapsulation and packaging materials.
High-performance LED devices can be produced by taking advantage of this material characteristics such as long-term durability, high-temperature stability, high adhesiveness, and high refractive index under high-temperature operation due to the high brightness LEDs.
When encapsulating the LED semiconductor chip used for the white light source, mix it with a phosphor.
Shin-Etsu have a wide range of silicone products from soft gels to hard types which can be applied for transfer molding. Shin-Etsu can supply grades that meet customer needs.
