isoflex topas ak 50

SOFLEX TOPAS AK 50 consists of synthetic hydrocarbon oil and aluminium complex soap. It protects against corrosion and is resistant to oxidation and ageing. In addition, it has good wetting properties and low internal lubricant friction.

  • ISOFLEX TOPAS AK 50 is suitable for the lubrication of plain and rolling bearings operating at high and/or low temperatures. It can also be used in small gears and plastic/steel as well as plastic/plastic components. It is compatible with many thermoplastics. 
  • The lubricant is applied by brush or conventional metering systems. Owing to the different compositions of elastomers and plastic materials, compatibility tests are indispensable before series application.
  • Lubricant for plastic components
  • High-speed grease
  • Good corrosion protection
  • Resistant to oxidation and ageing
  • Good surface wetting
