Product Overview

Polyester Series Products are a new type of synthetic ester-based lubricant base oil. They combine the dual performance advantages of synthetic esters and PAO (Polyalphaolefin), offering excellent lubricity. When compounded with anti-wear and extreme pressure (EP) additives, they demonstrate superior load-carrying capacity and extreme pressure performance.

The ester groups in their molecular structure provide a certain polarity, enhancing their affinity with metal surfaces. When blended with PAO or mineral oils, they exhibit a unique low-thickening effect while maintaining outstanding high-temperature resistance and shear stability. As a result, they are widely applicable in engine oils and gear oils.
