Lubricant additives

Our polymers perform as improved release lubricant additives in metal working fluids and can replace the oil-based products that have been used for decades.

Because of the high melt viscosity or their polar structure, these polymers release the friction partners and shift the metal working process towards hydrodynamic friction. These water-based polymer additives are responsible for a drastic reduction of the friction. Therefore, the temperature during metal working is significantly lower, which results in much better surface quality of the workpieces. Additionally, these water-based polymers exhibit less dermatological problems, no regulatory problems and no (or less) problems with labeling.

The strip drawing test

The strip drawing test simulates the conditions of a deep drawing process. It illustrates the effectiveness of the polymer additives and shows the difference between polar, highly viscous additives and a deep drawing oil as reference. In the strip drawing test, a metal strip coated with the respective lubricant, is drawn through two flat dies at a constant speed.

The upper tool adjusts the downholder from the deep drawing process and presses on the metal strip with a freely selectable force (contact tension). The coefficient of friction for the respective lubricant can be calculated mathematically from the measured tensile force and the contact tension.
