Base Oil Group – I

SN500

Description:
SN 500 is a Group I solvent neutral base oil produced through atmospheric distillation, solvent extraction, dewaxing, and hydrofinishing of crude oil. With a higher viscosity than SN 150 or SN 350, SN 500 is ideally suited for blending high-performance lubricants that require enhanced film strength, load-carrying capacity, and thermal stability. It is a key component in formulating heavy-duty engine oils, gear oils, and industrial lubricants.

Production Process:

• Solvent Extraction: Removes polar compounds and improves oxidative stability
• Solvent Dewaxing: Enhances low-temperature performance
• Mild Hydrofinishing: Improves color, stability, and purity

Key Technical Properties (Typical Values):

• Viscosity @ 100°C: ~10.5–11.5 cSt
• Viscosity Index (VI): 95–105
• Flash Point (COC): >230°C
• Pour Point: -6°C to -9°C
• Color (ASTM D1500):0–L3.0
• Sulfur Content: >0.03%
• Density @ 15°C: ~0.885 kg/L
• Aromatic Content: Moderate – improves additive solubility

Benefits:

• High viscosity for superior load-bearing and lubrication film strength
• Excellent solvency for dispersing performance additives
• Cost-effective solution for blending a wide range of heavy-duty lubricants
• Suitable for use as a blending stock with other Group I or Group II base oils
• Stable performance under high operating temperatures

Applications:

• Automotive: Diesel and gasoline engine oils, transmission and gear oils
• Industrial: Heavy-duty hydraulic fluids, compressor and turbine oils
• Marine & Railroad: Medium- to high-viscosity lubrication systems
• Greases & Metalworking: Suitable base stock for grease and cutting fluid production
• Rubber & Process Oils: As a process oil in manufacturing applications

Packaging Options:

• Available in bulk, IBCs (totes), steel drums, or flexitanks
• Custom formulation and blending services available

Compliance & Standards:

• Meets API Group I base oil specifications
• Suitable for formulations meeting various OEM and international performance standards
