By introducing phenyl groups into its molecular chain, methylphenyl silicone oil significantly improves its low-temperature fluidity. It maintains an extremely low freezing point and excellent viscosity-temperature characteristics across a wide temperature range of -70°C to 150°C, along with outstanding thermal and oxidative stability. Relying on these robust properties, it is widely used as a specialized lubricant for aviation timers, gyroscope motor bearings, and high/low-temperature precision instruments, serving as a core medium to ensure mechanical operation in extreme low-temperature environments.
