High-viscosity Polyolefine-polyester with Ester Groups


Ester PAO series is a kind of fully synthetic base oil for lubricants, with unique molecular structure, which is an olefin copolymer containing ester group, it is a high performance base oil which combines the performance of oil group IV and group V, combining the polarity/ function of ester and polyalphaolefinin the same macromolecule. It can obviously reduce friction, reduce wear, prevent foam formation, and control the formation of oil deposits, etc. Within a wider temperature range, ester-based PAO can form a high-strength lubricant film on many material surfaces, provide lubricating for a longer period of time; with excellent lubricating effects and thus extending the service life of equipment.


Ester-based PAO Features:

Easily improve lubricating performance by giving formulating technician more flexibility in balancing additives, increasing boundary lubrication and improving film thickness.

●Reducing friction and wear

● Excellent low temperature performance

● Improving shear stability

● Extremely high thermal oxidation stability

● Providing additive solubility

● Increasing the balance of       additives

● Higher viscosity index

● Compatibility of elastic seal balances

●Excellent lubricity and resistance to micropitting.



● Industrial lubricants

● Automotive lubricants

● Gear oils

● Food grade lubricants

● Engine oil

● Transmission oil

● Compressor oil

● Metalworking fluid

● High-temperature chain oil

● Steel cable oil, etc.

● Hydraulic oil

● Grease


Combustion cleanliness, low volatility

The ester-based PAO series burns or evaporates at high temperatures without producing hazardous fumes or carbon residues, making them ideal for use in low-smoke, environmentally friendly two-stroke engine or industrial gear oils.

When being used as a base oil, it is neutral to slight swelling characteristics to common sealing materials, and has the advantage without additional ester seal swelling agent when ultilized with PAO or group III base oils.
