Bright Stock 600N

Description

1. Product Overview

Bright Stock 600N is a high-viscosity, solvent-refined base oil derived from vacuum distillation residues, engineered for extreme-pressure and high-temperature lubrication environments. It serves as a critical viscosity builder and performance enhancer in industrial lubricants, greases, and heavy-duty engine oils. Strategically vital for markets demanding thermal stability and film strength, it enables asset-intensive industries to reduce mechanical wear, extend oil drain intervals, and lower total cost of ownership (TCO) compared to conventional bright stocks.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Highly refined paraffinic hydrocarbon with low aromatic content (solvent-extracted)

• Viscosity (ASTM D445): 600–650 cSt @ 40°C; 30–35 cSt @ 100°C

• Viscosity Index (ASTM D2270): Min. 95 (typical 98–102)

• Pour Point (ASTM D97): Max -9°C to -12°C

• Flash Point (ASTM D92 – COC): Min. 270°C

• Density @ 15°C (ASTM D1298): 0.890–0.910 g/cm³

• Sulfur Content: < 0.5% wt

• Appearance: Clear to bright amber, transparent liquid

• Noack Volatility (ASTM D5800): < 15% wt

• Packaging Options:

  • Bulk flexitanks (20 MT)

  • ISO tanks (24 MT)

  • Steel drums (180 kg net, 80 drums per 20’ container)

• Shelf Life: 36 months in original sealed container, non-hydroscopic

3. Core Industrial Applications

• Marine & Stationary Engine Oils (SAE 50, SAE 60):
  Provides superior oil film retention in cylinder lubrication of low-speed two-stroke crosshead engines. Reduces ring-to-liner wear by 30–40% versus monograde base oils.

• Heavy-Duty Gear Oils (ISO VG 460, 680):
  Used in mining haul truck differentials, wind turbine gearboxes, and steel mill reducers. Its high viscosity at operating temperature eliminates boundary lubrication failures.

• Industrial Greases (NLGI 2, 3):
  Acts as a thickening-enhancing base fluid for lithium-complex and calcium-sulfonate greases, improving dropping point and water washout resistance.

• Metalworking Formulations (neat oils):
  Applied in drawing, stamping, and broaching of high-tensile alloys where extreme pressure additives alone are insufficient.

Performance advantage: Bright Stock 600N maintains higher absolute viscosity at 100°C than lower-viscosity bright stocks (e.g., 150BS), directly translating into thicker elastohydrodynamic (EHD) films under slow-speed, heavy-load conditions.

4. Competitive Advantages

• Quality consistency: Produced under ISO 9001:2025 with batch-to-batch viscosity variation < ±3% – critical for regulatory-compliant formulations (API, OEM approvals).

• Supply reliability: Dual refinery sourcing (Middle East & Southeast Asia) with 20,000 MT monthly capacity. Dedicated pipeline to deep-water port eliminates trucking delays.

• Logistics capability: Temperature-controlled bulk vessels + rapid container loading (24-hour lead time for LCL/FCL from bonded warehouses in Rotterdam, Houston, Singapore, Jebel Ali).

• Price competitiveness: Direct upstream integration removes trader markups; 15–20% lower effective cost than EU or US Gulf Coast parity for equivalent quality.

• Sustainability & documentation: Low polycyclic aromatic (PCA) content (< 3% IP 346) compliant with EU REACH, US TSCA, and UK EA. Full Certificate of Analysis (CoA), Safety Data Sheet (SDS), and batch traceability included.

• Technical support: In-house tribologist consultation for custom blending specifications (viscosity blend charts, shear stability testing).

5. Commercial & Supply Information
