Product Code：SP3155
Product Name：Low RI Dimethyl Diphenyl Silicone Fluid
Product Introduction：
Manufactured from methyl chlorosilane and phenyl chlorosilane, this product is refined via hydrolytic cleavage, equilibrium polymerization and rectification to remove low-molecular substances. The refractive index is precisely regulated by adjusting the ratio of methyl groups to phenyl groups.
It is a colorless transparent oily liquid featuring low refractive index, excellent thermal stability across high and low temperatures, and strong oxidation resistance. It also delivers good electrical insulation, hydrophobicity, moisture resistance, lubricity and defoaming capability. With stable chemical properties, it is compatible with a wide range of media systems.
It is widely used as coupling medium for optical devices, insulating cooling fluid for electrical equipment, and industrial defoaming lubricant. It can also function as damping medium and moisture-proof protective oil, suitable for precision electronics, optical instruments, chemical production and other applications.
