klubersynth hlr 46-371

Klübersynth HLR 46-371 is an adhesive, pliant and high-temperature resistant special lubricating grease. Due to the product composition (base oil: polyalkylene glycol oil; thickener: special lithium soap) it is possible to use it in context with many elastomers which are sensitive to mineral oil (particularly EPDM) and plastics.

Outstanding performance data:

  • very wide service temperature range
  • good corrosion protection
  • good water resistance
  • excellent oxidation stability

Elastomer/metal or plastic/metal sliding material combinations, eg in car components

  • brake boosters
  • drum brakes
  • disc brakes
  • main brake cylinders
  • ABS
  • small gears (metal/plastic)
  • rolling bearings with EPDM sealing disks
  • radial shaft seals with EPDM elastomer

Compatibility with elastomers and plastics: The following elastomers were tested 168 h for compatibility with Klübersynth HLR 46-371 at 100 and 150°C. We recommend checking the compatibility of the lubricating grease and the contacting material, especially prior to series applications (our test results were obtained with samples and are not a substitute for your own testing).

  • Lubricating and assembly paste
  • Service temperature range – 40 / 150 °C
  • For elastomer/metal sliding material combinations
