What is Base Oil SN650?

Base Oil SN650 is a specific type of base oil that falls under the Group I category. It is a highly refined and purified base oil that offers specific performance characteristics suitable for a wide range of lubricant applications.


SN650 refers to the viscosity grade of the base oil, with “SN” indicating that it is suitable for use in lubricants and “650” representing its kinematic viscosity at 100 degrees Celsius. The kinematic viscosity of SN650 typically ranges from 600 to 700 centistokes (cSt) at this temperature.


Base Oil SN650 is known for its higher viscosity compared to SN150, making it suitable for applications that require thicker lubricating films and greater load-carrying capacity. It is commonly used in industrial lubricants, including hydraulic fluids, gear oils, transformer oils, and heavy-duty engine oils.


One of the key advantages of using Base Oil SN650 is its excellent thermal stability and resistance to oxidation. This allows lubricants formulated with SN650 to withstand high-temperature environments without breaking down or losing their lubricating properties. It helps protect machinery from excessive wear, corrosion, and deposit formation.


Additionally, SN650 offers good low-temperature fluidity, ensuring that the lubricant can flow and provide adequate lubrication even in colder conditions. It maintains its viscosity and lubricating properties across a wide range of temperatures, making it suitable for applications in various climates.


Base Oil SN650 is compatible with a wide range of additives, allowing formulators to tailor lubricant formulations to meet specific performance requirements. It can be blended with other base oils, viscosity modifiers, and performance additives to achieve desired viscosity grades and enhance performance characteristics.


When selecting Base Oil SN650 for a particular application, it is important to consider factors such as the operating conditions, equipment requirements, and lubricant specifications. Consulting with lubricant formulators or experts can help determine the optimal base oil and formulation for the desired performance objectives.


In summary, Base Oil SN650 is a highly refined base oil with a higher viscosity grade that falls under the Group I category. It offers excellent thermal stability, resistance to oxidation, and low-temperature fluidity, making it suitable for various industrial lubricant applications. Proper selection and formulation of lubricants using SN650 can help improve equipment performance, protect against wear and corrosion, and ensure reliable lubrication under demanding conditions.
