Klüber Noxlub KF 0921 is a fully synthetic long-term lubricating grease based on perfluorinated polyethers of high viscosity index. The grease covers a wide service temperature range even at temperatures down to -65°C.
NOXLUB KF 0921
- Klüber Noxlub KF 0921 is suitable for the long-term lubrication ofrolling or plain bearings requiring low starting torques in a variable environment along with the known advantages of PFPE lubricants.
- At temperatures as low as –65°C Klüber Noxlub KF 0921 is still pliant enough not to overload low-torque actuators, e.g. in the automotive or aerospace industries.
- Behaviour towards elastomers and plastics Lubricating greases based on polyether and PTFE are mostly neutral towards elastomers and plastics (except for perfluorinated rubber).
- Prior to series application, however, we recommend testing the lubricant compatibility with the materials in question.
- Wide service temperature range
- Good low-temperature properties
- Very good resistance to ambient media
- Good corrosion protection
- High oxidation stability
