Naphthenic Base Oil 500N

Description

1. Product Overview

Naphthenic Base Oil 500N is a high-viscosity, low-pour-point industrial fluid derived from carefully selected naphthenic crude stocks, offering exceptional solvency and thermal stability. It is primarily used as a base stock for industrial lubricants, transformer oils, and metalworking fluids where low-temperature performance and additive compatibility are critical. The key value proposition lies in its unique balance of high viscosity index stability and superior oxidation resistance, reducing system deposits and extending fluid life. Strategically, it is a vital enabler for reliable operations in cold-climate machinery, electrical infrastructure, and high-humidity environments—segments where paraffinic alternatives typically fail.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Highly saturated naphthenic hydrocarbons (low wax content, typically <0.5%)

• Purity / Grade: Technical grade; meets ASTM D6074 / Nynas or equivalent base oil classification

• Physical Characteristics:

  • Form: Clear, bright, stable liquid

  • Color: ≤ 2.5 ASTM

  • Viscosity @ 40°C: 90 – 110 cSt (centistokes)

  • Viscosity Index: ≥ 60 – 75 (typical)

  • Pour Point: ≤ –30°C to –40°C (depending on refining severity)

  • Density @ 15°C: 0.910 – 0.930 g/cm³

  • Flash Point (COC): ≥ 220°C

  • Aniline Point: 65 – 80°C (indicating high solvency)

• Packaging Options: Bulk ISO tanks, flexitanks (20,000L), 200L new/unwashed steel drums, IBC totes (1,000L)

• Shelf Life: 36 months minimum when stored in dry, covered conditions at 5–40°C, away from oxidants and moisture

3. Core Industrial Applications

• Primary Industries: Power generation (transformers), metal fabrication (rolling/cutting fluids), cold-chain logistics (hydraulics), rubber compounding, and marine lubricants.

• Specific Operational Use Cases:

  • Transformer oil dielectric fluids – Superior gas absorption and electrical insulation under thermal cycling.

  • Refrigeration compressor lubricants – Miscible with HFC/HFO refrigerants; resists wax precipitation at sub-zero temperatures.

  • Metalworking fluids (neat oils) – High solvency for grease, swarf, and additive packages; reduces tool wear and smoking.

• Performance vs. Alternatives: Unlike paraffinic 500N, Naphthenic 500N remains fluid down to –35°C, eliminates wax plugging in filters, dissolves polar contaminants more effectively, and lowers maintenance frequency by ~18–22% in cold-running systems. Cost advantage: Lower additive treat rates due to natural solvency.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 certified refining; each batch GC/MS-tested for aromatics and sulfur content (±2% batch-to-batch variance maximum).

• Supply Reliability: Multi-source feedstock agreements (Southeast Asia, Middle East, USGC) with 99.5% on-time delivery performance over 5+ years.

• Logistics Capability: Dedicated heated tanker fleet for cold-weather delivery; global hub warehouses (Rotterdam, Houston, Singapore, Jebel Ali) for 48-hour dispatch.

• Price Competitiveness: Direct refinery-to-market model removes 2–3 intermediary margins; volume discounts aligned with Platts benchmark minus premium for naphthenic cut.

• Sustainability & Benefits: Lower carbon footprint than PAO synthetics; fully recyclable as fuel blend end-of-life; REACH and RoHS compliant (no restricted SVHCs).

• Technical Support: Access to full data sheets (TDS, SDS, oxidation stability curves), application engineering team, and sample analysis (FTIR, viscosity aging) within 72 hours.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (MT) – equivalent to one flexitank or partial ISO tank consolidation.

• Loading Capacity per Container:

  • *20-ft standard container*: 20 MT (flexitank)

  • *40-ft container*: Not applicable for liquids (max 2x flexitanks at 40 MT unsafe) – use ISO tank instead.

  • *ISO Tank Container (20-ft frame)*: 24–26 MT net weight (depending on product density)

• Lead Time: 7–14 days for bulk truck/flexitank; 21 days for drummed/IBC orders (subject to port of loading).
