Pharmaceutical and personal care (cosmetic-grade silicone oils)
Digital printing and release coatings (anti-stick and leveling agents)
About Silicone Fluids
Chemical Structure
Silicone Fluid, mainly polydimethylsiloxane (PDMS), has the structure [–Si(CH₃)₂–O–]ₙ. Its siloxane backbone with methyl side groups provides high flexibility, thermal stability, and low surface tension—key to silicone fluid's lubricating, insulating, and hydrophobic properties.
Physical Properties
Silicone fluid features low viscosity-temperature coefficient, excellent thermal stability, wide operating temperature range (−60°C to 250°C), low surface tension, high dielectric strength, and strong water repellency. These properties make it ideal for lubrication, insulation, and defoaming applications.
About Silicone Fluids FAQs
Silicone fluid is used in a wide range of industries for lubrication, thermal insulation, dielectric cooling, antifoaming, and cosmetic formulations, due to its high thermal stability and low surface tension.
Yes. High-purity grades of silicone fluid are non-toxic, chemically inert, and biocompatible, making them suitable for use in cosmetics, pharmaceuticals, and medical devices.
Silicone fluids offer exceptional thermal stability, typically functioning between −60°C to +250°C. Specialty grades can tolerate even higher temperatures without decomposition.
Silicone fluid is strongly hydrophobic and insoluble in water, making it ideal for water-repellent coatings, release agents, and foam control in aqueous systems.
Compared to mineral oil, silicone fluid provides better temperature resistance, oxidation stability, dielectric strength, and longevity, especially in demanding or high-performance environments.

How to Choose the Right Silicone Fluid?
Choosing the right silicone fluid depends on your application’s specific performance needs. Key factors include:
Viscosity: Low-viscosity silicone fluids are ideal for lubrication and heat transfer, while higher viscosities suit damping, sealing, or dielectric use.
Thermal Stability: Ensure the fluid can handle your temperature range. Methyl or phenyl-modified fluids offer stability from −60°C to 250°C or more.
Chemical Compatibility: Select fluids that are inert and non-reactive with other system components to prevent degradation or cross-reactions.
Application-Specific Properties: Use high dielectric strength silicone for electronics, hydrophobic types for coatings, or medical-grade fluids for biocompatibility.
Consult technical datasheets to match fluid properties with performance needs.
Silico® silicone fluids offer reliable solutions across industries—engineered for consistency, safety, and performance.
