Greases are often reffered to as 'black magic'. We believe it is just a matter of knowing what to use and where in order to provide the best solution. Our line of greases is therefore almost unlimited: a wide variety of thickener technologies, base oils and additives according to the latest technology and development allows us to provide greases which provide performance that goes beyond most of the common industrial greases.

Organo clay (bentone)
Commercial bentone powder used as a thickener is basically an organophillic montmorillonite type of clay. They are formed by slurrying in the bentone powder in a portion of the oil, pre-gelling by adding a dispersant and stirring, then heating to drive off the remainder of the dispersant. Finally, the oil is blended in to adjust to the proper consistency. Bentones have a buttery texture, virtually no melting point, good adhesiveness, fair mechanical stability and poor rust preventative properties. They are valuable in high temperature applications and can be used as a multipurpose grease. The greatest disadvantage occurs if maintenance is neglected and an offing-out or breakdown of the grease occurs. The end result is bentonite clay in the bearing which will cause a rapid catastrophic failure of the system.
Silca based greases display very good pumpability and can be used in a wide range of applications, including aviation and at very high temperatures. The lack of fibrous structure can, however, result in excessive oil separation under pressure. This happens for example in centralized lubrication systems.
