Knowde Brand Highlights

Brand Overview: The refractive index determines the choice of a material for a lens in a given application. We supply LUMISIL^® in both refractive index variants:

High refractive index (HRI)

Normal refractive index (NRI)
LUMISIL® HRI Silicone: HRI LUMISIL^® combines high light efficiency with low gas permeability, which protects the inside of the LED against corrosion. HRI grades are therefore ideal for high-end applications in TVs and displays, as well as in car headlamps. LUMISIL^® HRI silicones are based on a technology developed and patented by WACKER.
LUMISIL® NRI Silicones: WACKER offers a number of NRI silicones that are highly efficient to process. NRI LUMISIL® grades are great for high-performance LEDs because they withstand large amounts of heat and radiation. One of many application areas here is general lighting, where costs and processing efficiency are key considerations.
