Polyalpha Olefins (PAOs) are premium synthetic hydrocarbon base oils used in advanced lubrication systems across the automotive, industrial, and aerospace sectors. Manufactured through the controlled polymerisation of alpha-olefins, PAOs deliver exceptional purity, consistency, and performance in the most challenging environments. They also have emerging application for use in immersion cooling systems in data centres.
Why Choose PAOs?
PAOs are highly regarded for their thermal and oxidative stability, which allows lubricants to last longer and supports extended service intervals. They perform exceptionally well across a broad temperature range, ensuring reliable operation of machinery even in extreme cold or intense heat. Their low volatility helps minimise oil loss and reduce emissions, particularly under high-temperature conditions.
PAOs also offer superior viscosity characteristics, maintaining consistent lubrication under fluctuating loads and speeds. Additionally, they are highly compatible with a wide range of additives and base stocks, making them an ideal choice for customised lubricant formulations.
Polyalpha Olefins Key Applications
Automotive & Transportation
Used extensively in high-end engine oils, transmission fluids, and gear lubricants, particularly in performance, electric, and long-drain service vehicles.
Industrial Lubrication
Ideal for compressors, turbines, and hydraulic systems where stability, efficiency, and reliability are critical under heavy loads or fluctuating temperatures. These benefits align with best practices outlined by industry groups like ATIEL and the NLGI.
Aviation & Aerospace
Trusted in jet engines and aerospace applications, thermal endurance and oxidation resistance are essential.
Polyalpha Olefins (PAOs) are trusted in jet engine and aerospace applications where extreme temperatures, high speeds, and oxidative stress push lubricants to their limits. With superior thermal stability and low volatility, PAO-based formulations ensure reliable performance at altitude and under pressure.
Electrical & Electronics
Found in dielectric fluids and advanced cooling systems, including those used in data centres and high-voltage equipment.
Food-Grade & Specialty Lubricants
PAOs also serve as the base for specialty lubricants, including NSF H1 food-safe products, where non-toxicity and stability are required.
Sustainability Through Performance
While PAOs are synthetic, they contribute to sustainability goals by:
- Reducing lubricant consumption through longer drain intervals
- Improving energy efficiency in engines and equipment
- Minimising environmental impact via lower emissions and reduced waste
