Description
- Service temperature range: -45°C to + 240°C
- high-quality brand of hightemperature lubricants based on perfluorinated polyether oil (PFPE)
- made using particularly fine PTFE thickeners and have an oil content that is unusually high for this type of grease
- Colour: white
- Size: 180g can
- also available as: can: 1kg
Benefits for your application
+ Long-term availability and service life of component
- 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
Application
- rolling and plain bearings operating at elevated temperature: long service lives when used in rolling and plain bearings operating under high thermal stress; smooth running of bearings also at high speeds and ensure a long life of the lubricated components; film stretchers, textile stenter frames, precision engineering, clean-room engineering (e.g. microchip manufacture)
- ultra-high vacuum application due to low vapour pressures
- electrical contacts: long-term lubrication of electrical contacts in high and medium-voltage switchboards
- widely neutral towards elastomers and plastics (possible exception: highly fluorinated rubber)
BARRIERTA is Europe’s oldest high-quality brand of high-temperature lubricants based on perfluorinated polyether oil (PFPE).
BARRIERTA products are among the most widely used PFPE lubricants today.
High-temperature greases of the BARRIERTA I series are made using particularly fine PTFE thickeners and have an oil content that is unusually high for this type of grease.
To suit various application purposes, BARRIERTA I greases are available in four different viscosities.
