INEOS Oligomers
INEOS Oligomers is the world's largest merchant marketer of polyalphaolefins (PAO) synthetic fluids marketed under the trade name Durasyn.


INEOS Oligomers is a global leader in the production of high-performance synthetic hydrocarbons, specializing in polyalphaolefins (PAOs) used across a range of industrial and automotive lubricant applications. With manufacturing facilities in North America, Europe, and Asia, INEOS Oligomers delivers consistent quality, innovation, and technical expertise to meet the evolving demands of formulators worldwide.
Their Durasyn® brand portfolio represents decades of R&D investment in advanced base fluids that provide superior oxidative stability, shear stability, and wide operating temperature ranges. This helps formulators design lubricants that perform under extreme operating conditions.


For formulators of lubricants and metalworking fluids, INEOS Oligomers’ Durasyn® PAO fluids represent a highly engineered base-fluid platform. These fluids are fully hydrogenated oligomers derived from alpha-olefins and are available in both low-viscosity (2–10 mm²/s at 100 °C) and high-viscosity metallocene PAO (mPAO) grades.
Key performance attributes:
- Exceptional low-temperature fluidity, enabling full lubrication very early during equipment start-up and reducing wear during cold conditions.
- Superior high-temperature film thickness, helping maintain protective lubricant films under heavy load and elevated temperatures.
- High viscosity index (VI) and engineered molecular uniformity, enabling more stable viscosity across the operating temperature range and minimizing reliance on large amounts of viscosity-modifier polymers.
- Excellent oxidative and thermal stability, which reduces deposit and varnish formation, extends fluid life, and lowers maintenance demands.
- High shear stability, meaning the formulated fluids maintain their viscosity grade and protective performance even under aggressive mechanical distortion.

As renewable energy capacity expands globally, INEOS Oligomers’ Durasyn® metallocene PAOs enable the next generation of high-performance wind turbine gear oils.
These fluids offer:
- High oxidative and thermal stability, extending lubricant life compared to mineral oils.
- Superior shear stability, maintaining viscosity and performance under severe gearbox conditions.
- High viscosity index (VI) and excellent low-temperature flow, allowing smooth startup and efficient performance in extreme climates.
- Low foaming tendency, enhanced micropitting resistance, and low volatility, ensuring reliability and long service life in demanding wind environments.
INEOS Oligomers also leads in single-phase immersion cooling solutions with its Durasyn® PAO range. These are synthetic base fluids that combine thermal efficiency, reliability, and sustainability.
These PAOs provide:
- Exceptional heat transfer capability for efficient cooling in high-performance environments like data centers.
- Eco-friendly properties—zero global warming potential, non-toxic, non-conductive, and non-flammable.
- High flash point and stability, ensuring safe operation and continuous cooling even in system failures.
