Synthetic Ester Lubricant Base Oil
Pentaerythritol ester base oil is a saturated polyol ester (POE) synthesized by the reaction of pentaerythritol with high- and low-carbon fatty acids. This structure provides excellent thermal stability, low volatility, and strong polarity, making it suitable for a wide range of high-performance synthetic lubricants.
This pentaerythritol ester base oil can be used independently or blended with other synthetic base oils, including PAO and high-quality mineral oils, to formulate advanced lubrication systems for demanding industrial and automotive environments.
Due to its excellent low-temperature fluidity, oxidation stability, and lubricity, it is widely used in applications such as aviation lubricating oil, refrigeration compressor oil, synthetic industrial gear oil, high-temperature chain oil, and air compressor lubricants.
The versatility of pentaerythritol ester base oil allows it to be used in a wide range of lubricant formulations:
Aviation Lubricating Oil
Suitable as a base oil for aviation turbine oil and aircraft lubricants, offering high thermal stability and low volatility under extreme operating temperatures.
Refrigeration Compressor Oil
Commonly used in refrigeration compressor oil for refrigerants R-22, R-32, R-134a, R-507, R-407C and R-410A, delivering excellent lubricity and chemical stability.
Synthetic Industrial Gear Oil
Provides excellent load carrying capacity and oxidation resistance for synthetic industrial gear oil formulations.
High Temperature Chain Oil
Used as a base oil for high temperature chain lubricant in industrial ovens, conveyors and processing lines.
Air Compressor Oil
Suitable for rotary screw compressor oil and high-performance compressor lubricants, helping improve oil life and thermal stability.
Internal Combustion Engine Oil
Applicable in ultra-low temperature engine oil formulations and high-performance synthetic lubricants.
High and Low Temperature Grease
Used as a base oil component in high temperature grease and low temperature grease formulations for demanding operating environments.
The molecular structure of pentaerythritol ester base oil provides outstanding resistance to oxidation and thermal degradation, supporting long service life in high-temperature environments.
The low pour point and high viscosity index make it suitable for low temperature lubricants and high temperature industrial oils.
A high flash point reduces evaporation loss and improves safety in high-temperature chain oil and aviation lubricants.
The natural polarity improves oil film strength and enhances adhesion to metal surfaces, helping improve lubrication performance in gear systems and compressors.
Provides reliable performance in applications exposed to moisture such as refrigeration compressor oils and industrial lubricants.
The ester structure contributes to environmentally friendly lubricant formulations.
