Applications of Base Oil SN 150

​

​

1. In the Automotive Industry:

   • Engine Oils: SN 150 is commonly blended with additives to produce engine oils that provide effective lubrication and protection for internal combustion engines.

   • Transmission Fluids: It is used as a base for automatic and manual transmission fluids, ensuring smooth gear shifts and reducing wear.

2. In Industrial Lubricants:

   • Hydraulic Oils: SN 150 is used in hydraulic systems to reduce friction and wear, providing efficient power transmission and system protection.

   • Gear Oils: It is a key component in gear oil formulations, providing the necessary lubrication and wear resistance for heavy-duty machinery and equipment.

3. In Metalworking Fluids:

   • Cutting and Grinding Oils: SN 150 is used as a base fluid in cutting and grinding oils, where its lubricity and cooling properties help improve the precision and longevity of tools and machined parts.

4. In Grease Production:

   • Lubricating Greases: SN 150 serves as a primary ingredient in the production of greases, where it helps provide long-lasting lubrication in bearings, joints, and other mechanical parts.

5. In Rubber and Tire Manufacturing:

   • Processing Oils: SN 150 is used as a processing oil in the production of rubber compounds, aiding in mixing and extrusion processes in tire and rubber manufacturing.

6. In Marine Lubricants:

   • Marine Engine Oils: SN 150 is a base oil used in marine lubricants for large engines, providing the necessary wear protection and stability in marine environments.

​

Safety and Handling:

Base Oil SN 150 is generally considered safe for industrial use, but proper handling is necessary to avoid environmental contamination and personal exposure. It is important to follow recommended guidelines for storage, transportation, and disposal, ensuring that the oil is kept away from open flames and direct sunlight to maintain its stability.

​

Comparison to Other Base Oils:

• Base Oil SN 500: Compared to SN 150, SN 500 has a higher viscosity and is better suited for applications requiring thicker lubrication, such as in heavy-duty industrial machinery.

• Synthetic Base Oils: While SN 150 is cost-effective and performs well in many applications, synthetic base oils offer better performance in extreme temperatures and longer service life, though at a higher cost.
