Klübertemp GR M 30N Vacuum Grease –
Temp Range (-60 to +200 (°C))
Long-term greases for a wide temperature range
Benefits
Long component life:
- over a wide service temperature range
- in contact with aggressive media
- where sensitive plastic materials are used
- under vacuum
Description
Klübertemp GR M greases are white, odourless, long-term greases based on perfluorinated polyether (PFPE) oils and polytetrafluoroethylene (PTFE) thickener. The extremely high viscosity index, i.e. the very flat viscosity curve of the base oils, allows excellent sliding friction properties across a wide service temperature range. Klübertemp GR M greases show a neutral behaviour towards most plastics and elastomers and can therefore be used for a variety of component materials.
Application
Klübertemp GR M greases are preferably used for the lubrication of small electric motors, controls and switches, plastic gears and seals where they show low breakaway torques, exceptionally low friction values as well as a reduced tendency to stick-slip.This leads, for example, to lower frictional heating of elastomers subject to dynamic loads and hence longer component life.
General behaviour towards elastomers and plastics
Lubricants based on perfluorinated polyether oils and polytetrafluoroethylene are generally regarded as neutral towards most elastomers and plastics (possible exception: highly fluorinated rubber). Nevertheless, compatibility with the materials should be tested, especially prior to series application.
Other application examples:
- Linear guides
- Small gears
- Clean room equipment
Application Notes
For optimum lubrication results, we recommend cleaning the friction points with white spirit 180/210 followed by Klüberalfa XZ 3-1. Then blow the surfaces with clean, dry air or hot air to remove solvent residues. For initial lubrication, the friction points must be clean and bright, i.e. free from oil, grease, perspiration and contamination. Klübertemp GR M greases may be applied directly or by means of brush, spatula or lubricant dispenser. The technical sales departments at Klüber Lubrication may be contacted at any time for advice to ensure optimum service life results.

It is strongly recommend using all fluids and greases at the time of receipt, however when storage is necessary, rotate older stock into use first and observe the recommended parameters listed below.
Klüber Grease
Shelf Life of Klüber Grease is a minimum of 5 years; in this case although there won't be problems in terms of chemical stability there can be oil separation over time, which is normal.
