Fluorosilicone oil and methyl silicone oil: performance breakthroughs in extreme environments
Chemical structure adaptability:


Fluorosilicone oil: Introducing trifluoropropyl (- C3F7) into the siloxane backbone, with a fluorine atom ratio of 15% -20%, a surface energy as low as 18mN/m, and a contact angle of up to 160 °.
Methyl silicone oil: The surface energy of the fully methyl structure is 22mN/m, with a contact angle of 110 °, and it exhibits excellent performance in conventional environments.
Extreme environmental applications:
Fluorosilicone oil: dominates the aerospace lubrication field, can withstand a wide temperature range of -80 ℃ to 300 ℃, and has a service life of over 10 years in satellite propellant systems; In semiconductor manufacturing, as a photoresist stripping solution, it is resistant to hydrofluoric acid corrosion.
Methyl silicone oil: accounts for 90% of conventional industrial lubricants, but degrades within 6 months in strong acid (pH<2) and strong alkali (pH>12) environments.
Cost benefit analysis: Fluorosilicone oil is 3-5 times more expensive than methyl silicone oil, but it is irreplaceable in scenarios such as nuclear facility protection and deep-sea exploration.
