ShinEtsu chemical developed low refractive index "KER-7000" series of packaging materials

ShinEtsu Chemical Co. Ltd. (Shin-Etsu Chemical) to develop a new generation of low refractive index silicon encapsulation material "KER-7000" series, greatly improving the reliability and the brightness of the light emitting tube two. And reduce the permeability. "KER-7000" series of two products, "KER-7080 A/B" and "KER-7030 A/B", the hardness is respectively 80 and 30. Samples are now available.

Good LED packaging materials need to have key performance: low permeability, high temperature and light stability, good light transmittance in the life cycle. If the permeability of the packaging material is high, oxygen and other gases are easy to penetrate easily lead to oxidation or vulcanization, which led to a decline in light intensity.

The packaging materials have developed the ShinEtsu chemical. Such as methyl silicon material has good heat resistance; phenyl silicon material with low permeability; the development of new "KER-7000" packaging materials not only air permeability than the phenyl silicon material is reduced by 10%, its heat resistance and methyl silicon can effectively resist high temperature, light intensity and reduce the corrosion caused by the degradation of peripheral materials. The refractive index of the new product is only 1.38, lower than the methyl silicon material, and the transparency is more excellent, suitable for the application of the LED.

ShinEtsu chemical industry also produces other HBLED application packaging materials. Such as mobile phones, notebook backlighting with the "SCR series" and LCD backlight "ASP series"; and chip bonding materials, lens materials, reflective filter materials and waterproof materials, etc..
