Synthetic Ester Lubricant Base Oil
This series of products is a kind of ester generated by the reaction of oleic acid and polyol, with excellent lubricity, biodegradable, good annealing purity, excellent high and low temperature performance, high flash point, high ignition point and other characteristics, can be used as a single base oil or synthetic base oil, can be used as a fire resistant hydraulic oil, metal processing oil
BASOILS TMP318 Series is an synthetic ester base oil developed for formulating fire-resistant hydraulic fluids and selected metalworking oils. Produced from oleic acid and polyol chemistry, it offers high lubricity, a high flash point, broad temperature performance, and strong formulation flexibility for industrial fluid manufacturers.
Available in TMP318-46 and TMP318-68 grades, this fire-resistant hydraulic fluid base oil can be evaluated as a primary base oil or a co-base oil in synthetic hydraulic fluid systems. It is especially suitable for applications where hydraulic equipment operates near heat sources, high-temperature machinery, or other environments where a conventional mineral-oil hydraulic fluid may present a higher fire risk.
The finished fluid’s fire resistance, compatibility, and application performance depend on the complete formulation. Final products should always be validated through relevant laboratory and application testing.
| Application | Recommended Dosage | Typical Use |
|---|---|---|
| Fire-Resistant Hydraulic Fluids | 10–98% | Ester-based hydraulic fluid formulations for industrial equipment operating in high-temperature or higher fire-risk environments |
| Metalworking Oils | 10–60% | Selected metalworking lubricant formulations requiring lubricity, high flash point, and broad temperature performance |
| Grade | Formulation Direction | Key Selection Considerations |
|---|---|---|
| TMP318-46 | Medium-viscosity hydraulic fluid formulations | Suitable where lower viscosity at 40°C, improved low-temperature flow, and responsive hydraulic operation are required |
| TMP318-68 | Higher-viscosity hydraulic fluid formulations | Suitable where a thicker lubricating film and higher operating viscosity are required |
The final grade should be selected according to the target finished-fluid viscosity, operating temperature, hydraulic pump design, additive system, low-temperature requirements, and seal-material compatibility.

Fire-resistant hydraulic fluid base oil is a base-oil component used to formulate hydraulic fluids for equipment operating near high-temperature processes or other environments where lower flammability risk is required. It is not a finished hydraulic fluid by itself.
TMP318 is described as an ester product formed from oleic acid and polyol chemistry. Its ester structure supports lubricity, high flash point, and broad temperature performance in suitable industrial fluid formulations.
Yes. The reference dosage for fire-resistant hydraulic fluid formulations is 10–98%. The actual use level should be determined by the required viscosity, additive package, finished-fluid performance targets, and validation results.
TMP318-46 has a lower viscosity range and lower pour point, making it more suitable for fluid formulations that require improved low-temperature flow. TMP318-68 provides a higher viscosity range for applications requiring a thicker oil film and higher operating viscosity.
Yes. The recommended reference dosage for selected metalworking oil formulations is 10–60%. Compatibility with other base oils, additives, metals, and process conditions should be verified before commercial use.
Do not publish a biodegradability claim unless BASOILS can provide grade-specific test reports, applicable test methods, and supporting technical documentation.
A base oil alone should not be claimed to meet a finished-fluid standard. The complete hydraulic fluid formulation must be tested and validated before stating compliance with a particular specification or fire-resistance classification.
