Phenyl silicone oil, modified with phenyl groups, offers superior flexibility at low temperatures, excellent thermal stability, and strong insulating properties. These features make it ideal for use in electrical and electronic equipment operating in sub-zero or extreme environments.

Maintaining fluidity below -90°C, it is suitable for lubrication, sealing, and heat dissipation in aerospace electronics, precision instruments, and cold-region electrical devices. Its resistance to oxidation, radiation, and moisture ensures long-term operational safety.

As a dielectric fluid or specialty lubricant, phenyl silicone oil plays a critical role in next-generation low-temperature electrical systems.
