    Product Highlights

    The use of Environmentally Acceptable Lubricants (EAL) are essential, especially in applications where accidental release into environmentally sensitive areas is possible. Equipment used in marine operations, ports/harbors, farming, forestry, golf courses and

    electrical transformers utilize synthetic ester based EALs to protect the environment, avoid costly clean-up charges/fines and achieve performance superior to mineral oils. Synthetic esters are well suited for use as base stocks and additives in aqueous and straight metalworking fluids due to their polar nature, which enables them to adsorb on metal surfaces, reducing friction and wear in the EHL and boundary lubrication regimes.

    Synthetic esters are widely used in both ferrous and non-ferrous cutting, rolling, forming and grinding applications. They can be readily emulsified to form stable synthetic and semi-synthetic fluids, and are useful as additives in straight or soluble oil formulations. Synthetic esters have low VOC and a favorable toxicological profile so they are worker friendly and environmentally responsible. Monoesters are manufactured from naturally occuring long chain fatty acids, primarily derived from renewable fats and seed oils. These simple ester molecules have a polar ester group that is attracted to metal surfaces while the hydrocarbon tail provides a lubricious layer that reduces friction and provides boundary lubrication. Monoesters have a low viscosity, high viscosity index (VI), good thermal stability and excellent biodegradability. These esters have an outstanding health and safety profile and some are popular ingredients for personal care products and cosmetics.

    Isopropyl and other branched esters (covered under US pat. 7,008,909) give outstanding hydrolytic stability and are preferred for water-based metalworking and textile applications. Monoesters are also used as lubricity additives in mineral oil and synthetic hydrocarbon lubricants to improve EHL and boundary lubrication.

    The low viscosity and high polarity of monoesters facilitate the removal of residual lubricant by washing after processing, important for metalworking and textile applications where surfaces must be free of residue that would impact plating, painting or dyeing.
