Phenyl silicone oil (Phenylmethylsilicone Oil) is a synthetic oil based on phenyl and methyl substituted silicone polymers. Its molecular structure gives it unique physical and chemical properties, such as excellent thermal stability, low volatility, good lubricity and chemical inertness. These characteristics make phenyl silicone oil show significant advantages in high-speed rotating equipment, especially in occasions requiring extreme temperature conditions, high vacuum environment or special requirements for lubricating materials.

1. Advantages of phenyl silicone oil in high-speed rotating equipment
(1) Excellent thermal stability
High temperature performance: Phenyl silicone oil can remain stable in a wide temperature range of -60℃ to +300℃, which is suitable for long-term operation of high-speed rotating equipment in high temperature environment.
Antioxidation: Compared with mineral oil and synthetic hydrocarbon lubricants, phenyl silicone oil has stronger antioxidant ability, is not easy to form deposits or colloids, and extends the service life of equipment.
(2) Low volatility
High vacuum adaptability: In vacuum or low pressure environments, the low volatility of phenyl silicone oil reduces the consumption and pollution of lubricating oil, and is suitable for use in semiconductor manufacturing equipment, vacuum pumps, etc.
