Applications of Phenyl Silicone Oil:
- Industrial Heat Transfer & Thermal Regulation
High-Temperature Heat Transfer Media: Due to its exceptional thermal stability and resistance to oxidation, the product is widely used as a heat transfer fluid in open systems, laboratory oil baths, and solar energy collection systems. It resists gelling and coking even at elevated temperatures (up to 250°C-300°C);
Low-Temperature Applications: Specific grades (Low Phenyl) offer outstanding cold resistance, remaining fluid at temperatures as low as -70°C, making them ideal for refrigeration systems and polar environment equipment.
- Specialty Lubrication & Hydraulic Fluids
Base Oil for High-Temp Greases: Acts as the primary base fluid for high-temperature greases (e.g., lithium or polyurea based) used in ball bearings, kiln cars, and conveyor systems where mineral oils would fail;
Vacuum Diffusion Pump Fluids: Its low vapor pressure and high resistance to oxidation make it an excellent working fluid for high-vacuum diffusion pumps in electronics manufacturing and metallurgy;
Damping Fluids: Provides stable viscous damping for meters, instruments, and torsional vibration dampers in automotive engines, owing to its high shear stability and excellent viscosity-temperature coefficient.
- Personal Care & Cosmetics
Hair Care (Serums & Oils): The high phenyl content provides a high refractive index, imparting superior gloss and shine to hair. It is non-greasy and improves the detangling and manageability of hair.
Color Cosmetics & Skin Care: Used in lipsticks, foundations, and sunscreens. It offers excellent compatibility (solubility) with organic ingredients (such as ethanol and organic sunscreens) and aids in the dispersion of pigments, providing a smooth, non-tacky skin feel.
- Optical & Electronic Applications
Optical Coupling Fluids: Used as a refractive index matching fluid for optical fibers and lens assemblies due to its high clarity and light transmission properties.
Dielectric Coolants: Serves as a dielectric coolant and insulator for transformers, capacitors, and high-voltage electronics, particularly where fire resistance and thermal stability are critical.
Specific performance (e.g., Low Temperature vs. High Refractive Index) depends on the phenyl content. Please consult the specific grade specifications (e.g., Low-Phenyl or High-Phenyl series) for optimal selection.
Package &Storage:
In 25kg and 200kg drum.
Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 36 months from the date of production. Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
