Lubricants
Hydraulic fluids play several important roles in the smooth operation of a well-balanced and well-designed hydraulic system. These include:
- Heat transfer
- Power transfer
- Corrosion prevention
- Lubrication

Additionally, hydraulic lubricants used in industries such as coal mining, iron and steel production, automotive manufacturing, the off-shore industry or used on aircraft and ships must have fire resistant properties.
Hydraulic lines can be subjected to very high pressures and if a hydraulic line in close proximity to an ignition source fails, there is a high potential for the system to catch fire and sustain a spray flame; which can result in catastrophic consequences. Fortunately, the widespread use of fire resistant hydraulic fluids has dramatically reduced the risk and limited the damage caused by fires resulting from hydraulic system failures.
We group our fire resistant hydraulic lubricant components under the generic descriptor of HF, and further classify according to their chemical composition under sub-groups such as HFA (emulsion or solutions containing more than 80% water), HFB (water in oil emulsions containing 45% water), HFC (polymer in water containing 35% water) and HFD (water free).
HFA (containing more than 80% water) & HFB (containing around 45% water)
In both these groups we offer a range of speciality emulsifiers and oleochemically derived synthetic ester base oils branded under industry recognised trade names of Atlas™, Brij™, Hypermer™, Tween™ and Priolube™. These products provide the formulator with the ability to control emulsion particle size, particle size distribution, longterm dynamic stability and to provide some degree of lubrication to the formulation.
HFC (containing around 30% water)
Our Emkarox ™ polyalkylene glycols provide outstanding shear stable thickening properties, excellent hydrodynamic lubrication properties, good compatibility with elastomers, good heat conductivity and excellent viscosity temperature profiles.
HFD (water free)
Our Priolube ester base oils are recommended for use where excellent lubrication, good oxidation stability, cleanliness of operation and low environmental impact are considered to be the main priority for the formulator.
