Base Oil Group I Bright Stock 500

Description

Product Overview
Base Oil Group I Bright Stock 500 is a high-viscosity, solvent-refined mineral oil derived from crude via conventional Group I refining. It is primarily used as a blending component to increase viscosity and improve film thickness in heavy-duty industrial lubricants, marine cylinder oils, and greases. The key value proposition is its ability to provide superior load-carrying performance and oxidation stability at a cost-effective price point compared to higher-group oils. Strategically, it remains indispensable in legacy and high-temperature applications where viscosity retention and solvency outweigh the need for hydrocracked purity.

Key Specifications & Technical Characteristics

• Chemical composition: Solvent-refined paraffinic mineral oil, Group I

• Purity level/grade: Technical grade, meeting API Group I specifications

• Physical characteristics:

  • Viscosity @ 100°C: 30.0 – 34.0 cSt

  • Viscosity Index: 95 – 105

  • Flash point (COC): ≥ 280°C

  • Pour point: -9°C to -15°C

  • Color: < 4.5 ASTM

  • Density @ 15°C: 0.895 – 0.920 g/cm³

• Packaging options: Bulk flexitanks (20MT), ISO tanks, or drums (180–200 kg net)

• Shelf life: 24 months in sealed, dry, contamination-free storage

Core Industrial Applications

• Primary industries: Marine lubricants, industrial gear oils, greases, metalworking fluids, railroad diesel engine oils

• Specific use cases: Blending high-viscosity marine cylinder oils (SAE 50, SAE 60); thickening lithium and calcium greases; compounding heavy-duty gear oils for mining equipment

• Why it performs better: Higher solvency and additive response than Group II/III in dark-colored or extreme-pressure formulations; lower volatility than lighter Group I grades, reducing oil consumption in hot-running engines

• Efficiency/cost advantage: Enables formulators to meet viscosity targets using less polymer thickener, directly lowering blend cost per liter

Competitive Advantages

• Quality consistency: Produced from single-source API-approved refineries with batch-to-batch COA guarantees

• Supply reliability: Available year-round from multiple strategic storage hubs (Rotterdam, Houston, Singapore, Jebel Ali)

• Logistics capability: Dedicated 20MT ISO tank and flexitank programs with 7-day lead times for key routes

• Price competitiveness: No premium for “water-white” specifications when color and solvency are the true performance drivers

• Sustainability & technical support: Full cradle-to-gate carbon footprint data available; on-call blending optimization support from tribologists

Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (bulk)

• Loading capacity per container: 20MT per 20-ft ISO tank or 22MT per flexitank in a 20-ft dry container (subject to weight limits per lane)
