Solvent Neutral Base Oil 600 SN

1. Product Overview

Solvent Neutral Base Oil 600 SN is a high-viscosity Group I base oil, refined through solvent extraction and hydrofinishing to achieve a controlled balance of viscosity, volatility, and additive response. It is primarily used as a feedstock in blending industrial lubricants such as hydraulic oils, gear oils, greases, and metalworking fluids. The key value proposition is its superior solvency and demulsibility compared to higher Group II/III oils, enabling cost-efficient formulations without compromising oxidation stability. Strategically, it remains critical in markets where asphaltenics removal and additive solubility drive performance, especially in legacy equipment and high-load, low-temperature startup conditions.

2. Key Specifications & Technical Characteristics

• Chemical composition: Saturated hydrocarbons (65–75%), mono- and di-aromatics (20–30%), polar compounds <1%; solvent extracted, hydrofinished

• Purity / Grade: Industrial lubricant base oil – Group I, 600 SN grade

• Physical characteristics:

  • Viscosity @ 40°C: 110–130 cSt

  • Viscosity index: 90–99 (min)

  • Flash point (COC): min 240°C

  • Pour point: max -9°C

  • Color (ASTM): max 4.0

  • Density @ 15°C: ~0.885–0.905 g/cm³

• Packaging options: Bulk (ISO tank, flexitank, tank truck), new steel drums (200L / 55 gal), IBC totes (1000L)

• Shelf life: 24 months in sealed, dry, contamination-free storage; protected from extreme heat or moisture

3. Core Industrial Applications

• Primary industries: Lubricant manufacturing, steel and heavy machinery, power generation, marine, mining, and tire release agents

• Specific use cases:

  • Blending industrial gear oils (ISO VG 460–680) requiring high film strength

  • Hydraulic oils for fixed industrial systems (non-high-pressure, water-separating environments)

  • Grease base oil for lithium or calcium complex thickeners

  • Metal rolling oils and process oils where solvency improves residue control

• Performance advantage: Superior solvency for anti-wear and detergent additives vs. severely hydrotreated base oils; better demulsibility and air release in wet systems; cost-effective for formulations that do not require high VI or low Noack volatility

• Efficiency gain: Reduces additive treat rates by 10–15% compared to Group II oils in compatible formulations, lowering total blend cost

4. Competitive Advantages

• Quality consistency: Lot-to-lot kinematic viscosity control within ±3% and color repeatability to ASTM within 0.5; ISO 9001 certified refinery source

• Supply reliability: Multiple origin options (Southeast Asia, Middle East, Europe) with safety stock buffer; average lead time 14–21 days ex-warehouse

• Logistics capability: Dedicated marine fleet and rail-fed loading points for 20MT–5,000MT shipments; demurrage risk mitigation through pre-vetting of carriers

• Price competitiveness: 10–18% price discount per metric ton to low-sulfur Group II equivalents, trading at index-linked pricing with volume rebates

• Sustainability / environmental: Compatible with used oil re-refining streams; lower hydrogen consumption in upstream production vs. Group II/III

• Technical support: Full COA, Viscosity-Temperature chart, additive compatibility matrix, and 24h technical inquiry response available

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (one bulk flexitank or ISO tank equivalent)

• Loading capacity per 20FT container: Not applicable for bulk liquid – typical shipment: 20–24 MT per ISO tank container; for drums: 80 drums / 16.0 MT per 20FT general purpose container
