Characteristics of Methyl Phenyl Silicone Oil
Methyl phenyl silicone oil is a type of organic silicon compound synthesized by replacing some methyl groups in methyl silicone oil molecules with phenyl groups. This structure endows it with a series of excellent properties:

High and low temperature resistance: With a wide operating temperature range, it can work stably between -50 ℃ and 250 ℃.
Thermal stability: After heating at 250 ℃ for thousands of hours, the physical properties remain basically unchanged.
Radiation resistance: It can still be used after receiving a radiation dose of up to 2 × 10 ⁸ R at room temperature.
Lubrication performance: The lubrication performance is superior to methyl silicone oil, making it suitable as a high-temperature lubricant.
Organic compatibility: Can be mixed with vegetable oil, animal oil, and mineral oil for use.
Low vapor pressure: suitable for ultra-high vacuum diffusion pump oil.
Low freezing point: Silicone oil with low benzene content (such as silicone oil containing 5% mole fraction of benzene) can reach a freezing point of -70 ℃, suitable for ultra-low temperature applications.


Application of Methylphenyl Silicone Oil
Methyl phenyl silicone oil has been widely used in various fields due to its excellent performance:
Aerospace and Electronics Industry:
As a high-temperature lubricant and insulating oil, used in aviation engines, electronic equipment, etc.
High vacuum diffusion pump oil is suitable for ultra-high vacuum environments due to its high thermal stability and low vapor pressure.
Cosmetics and Personal Care:
As a lubricant, it improves the softness and thermal stability of the formula.
Industrial lubrication and sealing:
Used for lubrication and sealing in high-temperature environments, such as metal processing and mechanical lubrication.
Coatings and sealants:
Used for preparing high-temperature and corrosion-resistant coatings and sealing materials.
