Polyol Ester POE Ester-based Oil for Engine Oils

Polyol Ester POE Ester-based Oil for engine oils

Description

SYN-2820HT Polyol Ester POE Ester-based Oil for engine oils is refined by the special treatment process after the reaction between neopenyl polyol with saturated fatty acid under a certain special process conditions. These series of ester-based oils are especially suitable for the use as the raw material of the engine oil with the viscosity grade 0W/16,0W/30,0W/40,0W/50 and so on.

They can be used with PAO,GTL oil and Group III hydrogenation oils(Blended with PAO or GTL, recommended dosage is 5~15%).   This series of ester-based oil belong to steric hindrance polyol esters, which have excellent oxidation stability, good antiwear performance, and excellent dissolution ability. This series of ester-based oil can swell the sealing materials, dissolve the insoluble additives, which can keep the additive stay balance.

They can dissolve the carbon deposition, which can ensure the engine to keep clean.   Engine oils formulated with these neopentyl polyol ester have longer oil change period and higher fuel economy. This kind of This series of ester-based oil can well adsorb on the friction interface because of their high polarity, working well at the moment of operation (90% of mechanical wear occurs at the start moment).

SYN-2820 ester-based oil has the excellent oxidation stability with low volatility and low carbon residue, high lubricity, low friction performance and excellent fuel economy.  

Key performance benefits
