Hydraulic fluids are essentially incompressible liquids that transmit power from a pump to a motor or actuator through a piping system. During operation, the system operates under pressure and the viscosity of the fluid must be high enough to minimize leakage and protect the pump from wear. Conversely, high viscosity hurts flow properties and efficiency at low temperatures if viscous drag becomes significant. Since hydraulic fluids may operate over a range of temperatures, the pour point and viscosity index are important. The fluid provides lubrication to the pump and valves and helps to prevent corrosion of metal parts. It must also be compatible with elastomeric sealing materials. The fluid must be formulated to guard against oxidation, hydrolysis and deposit formation, and it should not be toxic or harmful if accidentally discharged.
Hydraulic systems are commonly used in both mobile and stationary applications, therefore fluids must be designed to perform over a wide range of temperature and pressure service conditions. Synthetic esters offer shear stable, high viscosity index fluidity for excellent pump efficiency. They are preferred when biodegradability, fire resistance, wide temperature range, or other advanced performance characteristics are required. The International Standards Organization (ISO) classifies fire resistant synthetic ester fluids in the HFDU category, and several LEXOLUBE and LUBRICIT products can be used to achieve a Factory Mutual fire resistance certification. Several Z&S synthetic ester products are on the EU EcoLabel LuSC list and/or the NSF HX-1 list of acceptable components that can be selected to formulate H1 food grade lubricants. 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.
