By introducing bulky phenyl groups, phenyl silicone oil significantly enhances refractive index and optical transparency while maintaining excellent thermal stability and UV resistance. It can maintain stable light transmittance in high-temperature environments for extended periods and exhibits excellent compatibility with various optical resins. Thanks to these characteristics, it is widely used as a core base material for high-power LED packaging adhesives, optical fiber coatings, and high-refractive-index optical lenses, serving as a key material in the modern optoelectronics industry.
