To help formulators meet increasing demand for high lubricant performance and long product life, we offer a full line of Esterex™ esters, which includes adipate, neopolyol, phthalate and trimellitate esters. Esterex esters are well suited for a wide range of applications, including automotive, textile, industrial, aviation, turbine and compressor lubricants.
Esterex esters can be used as a stand-alone base stock or in combination with other fluids. Their compatibility with polyalphaolefin (PAO) and other base stocks available from ExxonMobil Product Solutions offers another solution for your formulation challenges. Most Esterex esters are inherently biodegradable,* making them an appropriate choice for applications in which a lubricant is in contact with the environment.
Key benefits
Thermal and oxidative stability for long drain intervals
Lubricity and cleanliness for durability in tough applications
Enhanced solvency for deposit prevention and seal swell
Readily or inherently biodegradable options
Tailored to meet your needs across applications

Proven performance
Ester solvency
To measure the solvency advantages of using Esterex esters in lubricant formulations, we used ASTM D611 (Standard Test Methods for Aniline Point and Mixed Aniline Point of Petroleum Products and Hydrocarbon Solvents). Compared to a 6 cSt and a 10 cSt PAO base stock, 5 cSt polyol and adipate esters demonstrate increased solvency.
