Buy Kluber BARRIERTA I MI-202 High-temperature long-term grease 180g can Dubai UAE

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.
