Base Oil Group – IV

PAO 6cSt

Description:
PAO 6 cSt is a medium-viscosity synthetic base oil belonging to the Group IV (Polyalphaolefin) category, derived from the polymerization of linear alpha-olefins (typically 1-decene). Engineered for performance and purity, PAO 6 offers a balance of high viscosity index, excellent oxidative stability, and low volatility, making it an ideal foundation for a wide range of premium engine oils, industrial lubricants, transmission fluids, and synthetic greases. Its consistent molecular structure ensures excellent additive solubility and long-term thermal reliability.

Production Process:

• Oligomerization of Alpha-Olefins: Produces uniform, branched synthetic molecules

• Hydrogenation: Removes unsaturated bonds, enhancing thermal and oxidative stability

• Fractionation: Provides precise viscosity control for reliable blending

Key Technical Properties (Typical Values):

• Kinematic Viscosity @ 100°C: ~5.8–6.2 cSt

• Kinematic Viscosity @ 40°C: ~30–32 cSt

• Viscosity Index (VI): ~135–145

• Flash Point (COC): >240°C

• Pour Point: -55°C to -60°C

• Color: Water-clear

• Sulfur Content: 0%

• Saturates: ~100%

• Volatility (NOACK): Very low

• Shear Stability: Excellent – retains viscosity in high-stress environments

Benefits:

• Exceptional oxidative and thermal stability for extended lubricant life

• Maintains viscosity and film strength across a broad temperature range

• Excellent cold-start performance and low pour point for severe environments

• Low volatility ensures low oil consumption and reduced emissions

• Compatible with a wide range of additives, esters, and synthetic base stocks

• Highly refined, water-clear appearance for precision blending and formulation

Applications:

• Passenger Car & Heavy-Duty Engine Oils: For premium SAE grades like 5W-30, 5W-40, 10W-40

• Automatic & Manual Transmission Fluids: Provides excellent shear and oxidation resistance

• Industrial Gear & Hydraulic Oils: Long-life, high-performance synthetic fluids

• Synthetic Greases: Acts as a thermally stable and clean base fluid

• Turbine & Compressor Oils: Used in systems requiring superior oxidative stability and purity

• Blend Component: Often combined with PAO 4, PAO 8, esters, or Group V oils for custom formulations

Packaging Options:

• Available in bulk, 200-liter drums, IBCs (totes), or flexitanks

• Custom blends, formulation support, and private-label options available
