Tony Daucorning will be launched for high brightness LED three kinds of high refractive index and low hardness of liquid packaging materials

Tony Daucorning (based in Tokyo) in order to meet the demand of high brightness LED, will be 08 years in early March listed three kinds of high refractive index and low hardness material "Dow Corning Toray OE-6550 package", "Dow Corning Toray OE-6520" and "Dow Corning Toray OE-6450". The refractive index was 1.53, Dow Corning Toray OE-6550 JIS A 50 level hardness elastic body (ELastomer), Dow Corning Toray OE-6520 JIS A 20 level low viscosity, low hardness elastomer, Dow Corning Toray OE-6450 is a high refractive index gel. The product is put into operation, it can be established to deal with the need to improve the performance and efficiency of LED packaging export system requirements.

The original LED packaging materials are mainly epoxy resins and other organic resins. Recently, with the improvement of LED brightness, the thermal stability is good, is conducive to improving the efficiency of the optical efficiency of the transparent silicon packaging materials demand.

LED chip packaging materials need to have the function, because of the appearance of the LED packaging design and different. For example, the lens (or lens) and packaging materials into a layer, in order to improve the operability of the production process, you need to lower viscosity, to ensure that the surface of the solid material. On the other hand, when the surface of the lens (or lens) and so on, as the chip protection layer requires moderate softness. In recent years, in order to improve the efficiency of light, the demand for high refractive index materials is also increasing
