G2820/G2823 Neopentyl Polyols Ester


This ester is manufactured by blending neopentyl polyols and saturated fatty acids, then refined by a special post-treatment process. It is a kind of steric hindrance polyol ester, with excellent oxidation stability and anti-wear property, excellent solubility.It is especially suitable for the basic raw materials of engine oil with viscosity grades such as 0w-16, 0w-20, 0W-30, 0w-40 and 0w-60. It is used in PAO, GTL oil and type III hydrogenation base oils.

Key functions : dissolving insoluble additives, making the additive balance; dissolving carbon deposition, to ensure the engine clean;

Common collocations: PAO, GTL, 5 to 15% added.


Product performance:

Excellent lubricity

High oxidation stability and thermal stability

Excellent hydrolysis stability

•  Excellent low temperature performance

Low volatility and low carbon deposition

Biodegradable, DCD65%

Outstanding solubility, expansive effect on rubber, solubilizing effect on insoluble additives, solubilizing effect on carbon residue, keeping cleanness



General engine oil (mineral oil +G2820/G2823) 5~15%;

High-end automotive engine oil (PAO/GTL+G2820/G2823) 5~25%;

Industrial gear oil and wind power generation gear oil 5~10%;

Adding neopentyl polyol ester to internal combustion engine oil enables to extend drain intervals and improve fuel economy. The high polarity of the synthetic ester allows the ester to adsorb very well to the frictional working interface and is immediately functional at the moment of operation (90% of mechanical wear occurs at the moment of start-up). G2820 / g2823 ester, excellent oxidation stability.Low volatility and low residual carbon. Prolonged oil change intervals. High lubricity and low friction. Excellent fuel economy.
