Base Oil GP 500 (Group I)

Description

1. Product Overview

Base Oil GP 500 is a high-viscosity Group I mineral base oil, solvent-refined from selected paraffinic crude stocks to deliver exceptional oxidation stability and low volatility. It is primarily used in industrial lubricant blending, heavy-duty grease manufacturing, and high-viscosity metalworking fluids where thermal stability and film strength are critical. With its balance of solvency and cost-efficiency, GP 500 remains a strategically indispensable raw material for emerging markets and legacy systems that cannot transition to higher Groups without retrofitting equipment.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Highly refined paraffinic hydrocarbons; solvent-extracted and hydrofinished

• Viscosity Grade: ISO VG 460–500 (ASTM D445)

• Viscosity Index (VI): 90–99 (ASTM D2270)

• Flash Point (COC): ≥ 280°C (ASTM D92)

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

• Sulfur Content: < 0.8 wt%

• Appearance: Bright, clear, and free from sediment

• Physical Form: Amber liquid at room temperature

• Density @ 15°C: 0.895–0.915 g/cm³

• Packaging Options:

  • Bulk (ISO tanks, flexitanks)

  • 200L new/unreconditioned steel drums

  • IBC totes (1,000L)

• Shelf Life: 24 months in original sealed container under dry, ambient conditions

3. Core Industrial Applications

• Industrial Gear Oils: GP 500 provides superior film thickness in heavy-load, slow-speed gearboxes (e.g., cement mills, mining conveyors), outperforming lower-viscosity oils by reducing metal-to-metal contact.

• Marine Cylinder Oils (as blend stock): Used in 2-stroke crosshead diesel engines for ships; its high base number retention and demulsibility prevent ring sticking and cylinder liner wear.

• Grease Manufacturing: Ideal base for lithium, calcium, and aluminum complex greases used in heavy machinery; offers excellent bleed stability and shear resistance.

• Metal Rolling Oils (non-ferrous): Superior solvency removes rolling debris; lower volatility reduces fume generation during high-temperature aluminum rolling.

• Cost advantage over Group II/III: For equipment designed before 2005, GP 500 remains fully compatible with seals, paints, and varnishes that higher Groups can attack — eliminating costly retrofits.

4. Competitive Advantages

• Quality Consistency: Every batch meets or exceeds API Group I specifications; viscosity and VI variation < 2% across shipments.

• Supply Reliability: Dedicated Group I production line with 2+ global refineries; buffer stock maintained in Rotterdam, Houston, and Singapore hubs.

• Logistics Capability: 48-hour dispatch ex-stock from regional warehouses; door-to-door delivery with real-time temperature monitoring for winterized routes.

• Price Competitiveness: 12–18% lower per metric ton than Group II equivalents when adjusted for solvency performance; no premium for high-viscosity cuts.

• Sustainability: Refinery ISO 14001-certified; base oil is fully recyclable with standard re-refining technologies; 30% lower carbon footprint than newly produced Group III due to lower hydrogen intensity.

• Technical Support: Full documentation package (COA, SDS, viscosity-temperature charts, seal compatibility matrix); on-call lubrication engineers for blend formulation.
