Description
Klüber BARRIERTA I EL-102 is a high-temperature grease based on PFPE and thickened with PTFE, specifically developed for long-term lubrication in demanding industrial applications—from microelectronics to mechanical engineering.
- Outstanding protection up to 180 °C
- Resistant to aggressive chemicals and vapors
- Excellent compatibility with plastics and elastomers
- Pack size: 1 Kg can (Item no. 0900080037)
- Also available in: 50g tube / 180g can
Application Areas
- Rolling and plain bearings operating at elevated temperature
BARRIERTA I greases attain long service lives when used in rolling and plain bearings operating under high thermal stress.
The fine thickener and the high oil content enable smooth running of bearings also at high speeds and ensure a long life of the lubricated components.
Typical fields of application are in
- film stretchers
- textile stenter frames
- precision engineering
- clean-room engineering (e.g. microchip manufacture)
The low vapour pressures of BARRIERTA I greases make them also recommendable for use in fine to ultra-high vacuum.
- Electrical contacts
BARRIERTA I EL-102 and BARRIERTA I MI-202 have proven successful for the long-term lubrication of electrical contacts in high and medium-voltage switchboards. Component tests have shown that plug and unplug forces are consistent without unduly influencing transition resistance. There are no known decomposition products
that would have an insulating effect on the contacts.
Behaviour towards plastics and elastomers BARRIERTA I greases of all viscosity grades are widely neutral towards elastomers and plastics (possible exception: highly
fluorinated rubber). Nevertheless, compatibility with the materials should be tested, especially prior to series application.
Benefits for Your Application
- Long-term availability and service life of components
- over a wide service temperature range up to 260°C
- when exposed to aggressive chemical agents and vapours
- when using sensitive plastic materials
- Tried and tested over many years in numerous industries and component types
- due to BARRIERTA base oils, which are made specifically to enable long-term stability
- backed by a large number of approvals and references
- due to availability in 4 different viscosity grades to suit various applications
