Kluberalpha GR ZNF High Vacuum Grease (formally known as Fomblin ZNF) is a homogeneous, PTFE based grease, exhibiting good surface adhesion and wear resistance properties. 100 gm.

  • Wide service temperature range (-60 to 200°C)
  • Very high evaporation stability
  • For applications under vacuum conditions
  • Good adhesion to many materials
  • Chemically inert to avoid undesirable reactions

Kluberalfa GR ZNF is preferred for applications under vacuum conditions or strong temperature fluctuations. Application include cleanroom equipment, semiconductor or automation technology as well the aerospace industry. Kluberalfa GR ZNF also exhibits good sliding friction behavior and can be used in linear guides, rolling and plain bearings and seals.

Lubricants based on fluorinated polyether oils and polytetrafluoroethylene are generally regarded as neutral towards most elastomers and plastics (exception: perfluorinated rubber). Nevertheless we recommend testing compatibility with the material to be used.
