In the ongoing development of LED lighting and optoelectronic devices towards higher brightness and higher luminous efficiency, the refractive index matching of packaging materials has become a key factor affecting the out-coupling efficiency of the devices. The interface reflection loss caused by refractive index mismatch can significantly reduce the light extraction efficiency of LEDs. Our company's product, high refractive index plasticizer 9006, as a colorless transparent high refractive index organic silicone fluid, with its excellent refractive index adjustment ability, good thermal stability and antioxidant properties, demonstrates significant application value in the refractive index regulation of LED packaging adhesives, providing a precise medium solution for the optimization of the optical performance of optoelectronic devices.


I. Core Physical and Chemical Properties of the Product


Product high refractive index plasticizer 9006 is a colorless transparent oily liquid with a viscosity of 15 to 50 square millimeters per second at 25 degrees Celsius. Its refractive index range is from 1.5440 to 1.5710, and its relative density is from 1.04 to 1.07. The chemical composition of this product is tetramethyltetraphenyltrisiloxane. The high refractive index is due to the high proportion of phenyl groups in the molecular structure, and its low viscosity characteristic makes it easy to disperse and precisely mix in the packaging material formulation.
