Synthetic Ester Lubricant Base Oil
Trimethylol propane is a high quality saturated polyol ester that can be used alone or in combination with other synthetic materials as a base oil for a variety of fully synthetic or partially synthetic lubricants. With good high and low temperature performance, it is suitable for the production of ultra-low temperature synthetic lubricating oil which can be used as ultra-low temperature internal combustion engine oil, aviation lubricating oi and so on.
BASOILS Trimethylolpropane Ester Base Oil is a synthetic ester base oil developed for fully synthetic and semi-synthetic lubricant formulations requiring excellent low-temperature fluidity, high viscosity index, thermal stability, and low volatility.
Available in a range of low- to medium-viscosity grades, the TMP ester series can be used as a primary base oil or as a co-base oil with compatible PAO and selected mineral base oils. Its balanced viscosity-temperature performance makes it suitable for lubricant systems operating under cold-start conditions, temperature fluctuations, high-speed motion, and extended service intervals.
This series is particularly suitable for ultra-low-temperature internal combustion engine oils, aviation lubricant formulations, compressor oils, hydraulic fluids, greases, aerosol lubricants, and industrial gear oils.

This guide is for initial selection only. Final grade selection should be based on the target finished-oil viscosity, operating temperature, additive system, volatility target, equipment design, and required performance testing.
Trimethylolpropane ester base oil is a saturated polyol ester used in synthetic lubricant formulations. It is commonly selected for applications requiring low-temperature fluidity, high viscosity index, thermal stability, and low volatility.
Yes. The TMP607 grade has a pour point of -70°C, while other grades offer pour points from -60°C to -53°C. These properties make the series suitable for evaluating ultra-low-temperature lubricant formulations.
Yes. The current application guidance lists aviation lubricating oil as a recommended use, with a maximum reference dosage of up to 98%. Final aviation lubricant performance must be validated against the required specification and application conditions.
Yes. TMP ester base oil can be evaluated in blends with compatible PAO and selected mineral base oils. Before commercial use, formulators should verify miscibility, viscosity response, additive solubility, seal compatibility, and finished-lubricant stability.
Grade selection depends on the target finished-fluid viscosity, low-temperature requirement, hydraulic pump design, additive system, and final fluid performance target. TMP107, TMP108A, TMP108B, TMP108C, and TMP108D may be evaluated as starting options.
Yes. The recommended formulation range for high- and low-temperature grease is 10–90%. Final selection should be tested with the intended thickener system and additive package.
