Product Code：SP3150
Product Name：Low RI Methyl Phenyl Silicone Fluid
Product Introduction：
This product is refined from methyl chlorosilane and phenyl chlorosilane via hydrolytic cleavage, equilibrium polymerization and rectification for low-molecular-weight removal. The refractive index is precisely controlled by adjusting the ratio of methyl groups to phenyl groups.
It is a colorless transparent oily liquid with low refractive index, excellent high and low temperature stability and good oxidation resistance. It also features superior electrical insulation, hydrophobicity, moisture resistance, lubricity and defoaming performance. With stable chemical properties, it is compatible with various medium systems.
Widely applied as coupling medium for optical devices, insulating cooling fluid for electrical equipment, and industrial defoaming lubricant, it can also serve as damping medium and moisture-proof protective oil. It is suitable for precision electronics, optical instruments, chemical production and other fields.
