Product Code：SP3255
Product Name：High RI Dimethyl Diphenyl Silicone Fluid
Product Introduction：
This product is prepared from high-phenyl-content silane monomers via hydrolytic copolymerization, molecular structure regulation and vacuum rectification. The refractive index is accurately increased by raising the proportion of phenyl groups.
It is a colorless, transparent oily liquid with a high refractive index and excellent optical transparency. It features superior resistance to extreme temperatures, aging and radiation, along with reliable electrical insulation and chemical stability. It is resistant to corrosion and oxidation and offers excellent optical compatibility.
It is mainly applied to optical lens filling, coupling and bonding of optical components, and LED optoelectronic packaging. It can also be used as high-end optical damping medium and moisture-proof insulating oil for precision instruments, ideal for high-end manufacturing sectors such as optoelectronics and optical instruments.
