Introduction
As a synthetic ester base oil, polyester combines the advantages of synthetic esters and Poly α Olefin (PAO) and performs well in lubrication performance.
Under extreme working conditions, this material can effectively improve the oil film strength and load-bearing capacity when used with anti-wear extreme pressure additives due to its outstanding HTHS stability.
This unique comprehensive performance makes it an important basic component of modern internal combustion engine oil and industrial gear oil formulations.
