In LED packaging and high-end optical lens manufacturing, maximizing light transmission is key to enhancing product performance. While ordinary methyl silicone oil offers good transparency, its low refractive index limits light extraction efficiency. Enter Phenyl Silicone Oil, which has become a "high-light" material in the optoelectronic field thanks to its unique molecular structure. The introduction of benzene rings onto the side chains of Phenyl Silicone Oil not only endows it with a higher refractive index (typically between 1.46 and 1.56) compared to standard silicone oils but also significantly boosts heat and radiation resistance. Incorporating Phenyl Silicone Oil into LED encapsulants acts like a "condenser lens" for the chip, significantly reducing total internal reflection losses and enhancing brightness. Additionally, it is frequently used in the cosmetics industry, where its superior gloss and spreadability impart a captivating radiance to lipsticks and foundations.
