Base Oil Group I SN 150

1. Product Overview
Base Oil Group I SN 150 is a solvent-refined, high-viscosity mineral oil engineered for lubricant manufacturing and industrial formulations. It serves as a cost-effective base fluid for hydraulic oils, metalworking fluids, and general-purpose greases. Its balanced volatility and solvency deliver reliable performance in non-severe operating conditions. Strategically, it remains the global workhorse for price-sensitive markets requiring dependable specification compliance.

2. Key Specifications & Technical Characteristics

• Chemical composition: Solvent-refined paraffinic mineral oil (CAS 64741-88-4)

• Purity level: >99% base oil; additive-free

• Physical characteristics:

  • Form: Clear, bright liquid

  • Color: ≤2.5 ASTM

  • Viscosity @40°C: 28–32 cSt

  • Viscosity index: ≥90

  • Flash point (COC): ≥215°C

  • Density @15°C: 0.87–0.89 g/cm³

3. Core Industrial Applications

• Primary industries: Lubricant blending, metalworking, rubber processing, transformer oil manufacturing

• Specific use cases:

  • Hydraulic oils (ISO 32–68 grades)

  • General-purpose industrial gear oils

  • Low- to moderate-duty circulating oils

  • Base for rust preventives and process oils

• Performance advantage vs. alternatives: Delivers higher oxidation stability and lower volatility than re-refined or unrefined streams. Outperforms Group II on price in applications not requiring high Viscosity Index. Provides better additive solubility than highly hydrotreated oils, reducing blend complexity and cost.
