Naphthenic Base Oil 500N

1. Product Overview

Naphthenic Base Oil 500N is a refined, low-aromatic hydrocarbon oil derived from naphthenic crude, characterized by low pour point and high aniline point. It is primarily used as a process oil in transformer oil formulations, rubber compounding, and industrial lubricants. The key value proposition lies in its ability to deliver excellent solvency power and thermal stability without paraffin wax interference. Strategically, it fills a critical gap for buyers requiring naphthenic viscosity grades above 350N, balancing performance and cost in cold-climate and high-dissipation applications.

2. Key Specifications & Technical Characteristics

• Chemical composition: Naphthenic hydrocarbons (>70% cyclic saturates), <0.5% aromatics, sulfur <0.1%

• Purity / grade: Technical grade (Group V base oil), non-carcinogenic, low PAH

• Physical characteristics: Clear amber liquid; viscosity 95–110 cSt @ 40°C; density 0.895–0.920 g/cm³ @ 15°C; pour point ≤ –30°C; flash point (COC) ≥ 220°C

• Packaging options: Bulk ISO tank, flexitank (20MT), 200L steel drums (net 180kg), IBC totes (900kg)

• Shelf life: 36 months in sealed, dry, non-oxidizing conditions (original packaging)

3. Core Industrial Applications

• Transformer oil blending: Low pour point and high oxidation stability reduce sludge formation, extending insulation life by >20% compared to paraffinic alternatives.

• Rubber compounding (extender oil): High solvency allows faster polymer absorption and uniform dispersion in EPDM, SBR, and NR, improving tensile strength and reducing mixing energy.

• Metalworking fluids: Superior wetting and residue-free evaporation prevent rust during intermediate machining steps, lowering reject rates in precision manufacturing.

• Drilling fluids (offshore/arctic): Maintains viscosity at sub-zero temperatures, avoiding wax crystallization that blocks circulation in deep-sea risers.
