re refined base oil SN500

Re-refined base oil SN500 is a high-quality lubricant base stock derived from used oils through advanced re-refining processes. This environmentally friendly alternative to virgin base oils offers comparable performance characteristics, making it suitable for various industrial and automotive applications.

Properties of Re-refined Base Oil SN500:

• Kinematic Viscosity at 100°C: Typically ranges from 9 to 11 cSt, ensuring effective lubrication under high-temperature conditions.
• Flash Point: Between 240°C and 260°C, indicating a high resistance to ignition and suitability for high-temperature applications.
• Pour Point: Ranges from -5°C to 0°C, ensuring fluidity in lower temperatures and adaptability to various climates.
• Density at 15°C: Approximately 0.865 to 0.875 kg/l, reflecting its composition and purity.
• Color: Rated between 1.5 and 2 on the ASTM D-1500 scale, indicating a light appearance, which is often associated with higher purity levels.

Re-refining Process:

The re-refining process involves several key steps to transform used oils into high-quality base oils:

• Dehydration: Removal of water content through evaporation.
• Vacuum Distillation: Separation of oil fractions under reduced pressure to prevent thermal degradation.
• Hydrotreating: Use of hydrogen to eliminate impurities, enhance color, and improve oxidation stability.
• Filtration and Finishing: Final purification to meet industry standards.

This process not only conserves natural resources but also reduces environmental pollution by recycling used oils.

Applications:

Re-refined base oil SN500 is versatile and used in various applications, including:

• Lubricant Production: Serves as a primary component in formulating engine oils, transmission fluids, and industrial lubricants.
• Hydraulic Oils: Provides the necessary viscosity and stability for hydraulic systems.
• Metalworking Fluids: Acts as a base for cutting oils and other metal processing lubricants.
• Grease Manufacturing: Used in the production of various greases for automotive and industrial applications.

Environmental Benefits:

Utilizing re-refined base oils offers significant environmental advantages:

• Resource Conservation: Reduces the demand for virgin crude oil extraction.
• Energy Efficiency: The re-refining process consumes less energy compared to producing base oils from crude oil.
• Waste Reduction: Mitigates the environmental impact of used oil disposal by recycling it into valuable products.

Quality Assurance:

Modern re-refining technologies ensure that re-refined base oil SN500 meets stringent industry standards, offering performance on par with virgin base oils. Regular testing and quality control measures, such as those outlined in ASTM methods, are employed to maintain consistency and reliability.

In summary, re-refined base oil SN500 is a sustainable and high-performance option for various lubrication needs, combining environmental benefits with economic advantages without compromising on quality.
