Synthetic Ester Lubricant Base Oil
Trimellitate esters are esters formed by the reaction of trimellitic anhydride with mono alcohol and polyol. It has a high flash point, low volatility, especially suitable for the application of high temperature conditions, can be used as high temperature chain oil base oil, air compressor oil, high and low temperature grease. It can also be used in combination with PAO and high-quality mineral oils, and can be used as a base oil for a variety of fully synthetic or semi-synthetic lubricants.
Trimellitate Ester Base Oil is a synthetic ester base oil series developed for lubricant formulations operating under elevated temperatures, heavy loads, and long service intervals.
Produced from trimellitic anhydride and selected monoalcohols or polyols, trimellitate esters offer a useful balance of high flash point, low volatility, low-temperature fluidity, and thermal stability. The series is available in multiple viscosity grades, allowing lubricant formulators to select a suitable base oil for high-temperature chain oils, air compressor oils, industrial gear oils, and high- or low-temperature grease systems.
The products can also be evaluated in blends with compatible PAO and high-quality mineral base oils. Final blend ratios should be selected according to viscosity targets, additive compatibility, equipment design, and finished-lubricant performance requirements.

Trimellitate ester base oil is a synthetic ester lubricant base oil made using trimellitic anhydride and alcohol components. It is commonly considered for high-temperature lubricant formulations requiring high flash point, low volatility, and broad viscosity selection.
Yes. The series can be used at up to 98% in high-temperature chain oil formulations. The final formula should still be verified for volatility, cleanliness, oxidation stability, residue control, and equipment-specific requirements.
Yes. The published application guidance allows use up to 98% in air compressor oil formulations. Grade selection should depend on compressor type, discharge temperature, target viscosity, and finished-lubricant testing requirements.
Yes. It can be evaluated in blends with compatible PAO and selected high-quality mineral base oils. Before commercial use, formulators should verify miscibility, viscosity response, additive solubility, seal compatibility, and finished-oil stability.
The appropriate grade depends on the target finished-oil viscosity, operating temperature, load conditions, and additive system. TM220 through TM2000 may be evaluated for higher-viscosity gear oil and grease systems, subject to formulation testing.
Yes. The suggested reference dosage range for high- and low-temperature grease is 10–90%. Final performance should be validated with the selected thickener system and additive package.
