Application

Polymeric Esters are primarily used in applications requiring high lubricity and stability, as detailed below:

Gear oils: Polymeric Esters serve as base oil or additive component in high-performance gear oils.

Heavy-duty metalworking fluids: Polymeric Esters can replace chlorinated paraffins as an extreme-pressure additive and exhibit good synergistic effects with sulfur-phosphorus extreme-pressure agents.

Automotive lubricants: In two-stroke and four-stroke engine oils, polymer esters enhance lubricity and anti-wear performance.

Features

High lubricity.
Synergistic effect with anti-wear/extreme pressure (AW/EP) additives to deliver outstanding load-carrying and EP performance.
Polar ester group adsorbs to metal surfaces to boost anti-wear performance and extend equipment life.
Compatible with mineral base oils and (Polyalphaolefin) PAO.
High thermal and oxidative stability, low evaporation loss.
Excellent shear stability.
