What are ester oil benefits in Lubricants?

Synthetic ester oils were developed during World War II for their excellent low-temperature performance, vehicles & airplanes with ester-based engine oil can still work in extreme cold weather.

Nowadays, synthetic ester lubricants are now widely used in aerospace engine oils, automobile and marine engine oils, compressor oils, hydraulic oils, gear oils, and other fields due to their excellent performance:

1. Good viscosity-temperature characteristics: Ester oil has good viscosity-temperature characteristics and a high viscosity index.
2. Good low-temperature performance: The diester with branched alcohol usually has a lower freezing point. The freezing points of commonly used sebacic acid ester and azelaic acid ester are all below -60°C.
3. Good high-temperature performance: For the same type of ester, the flash point increases and the volatility decreases with the increase of relative molecular weight.
4. Good lubricity: the ester molecule is easily adsorbed on the friction surface to form a boundary oil film, so the lubricity of ester oil is generally better than that of mineral oil with the same viscosity. It has good anti-wear, anti-scratch and friction characteristics.
5. Biodegradable: This is a unique feature of ester oil compared to other synthetic oils and mineral oils. Among the oils currently on the market, most of the so-called Eco-friendly motor oils are blended with ester oil as the base oil.
6. Good oxidation stability: One of the characteristics of ester oil is good oxidation stability, but it also varies due to its different structure. Anti-oxidation and anti-corrosion additives are still required in actual use.
