BARRIERTA L 55

High-temperature long-term greases.

Your demanding application requires a high-quality lubricant of the highest quality and excellent lubrication properties.

BARRIERTA is Europe's oldest high-quality brand of hightemperature lubricants based on perfluorinated polyether oil (PFPE). Today the name of BARRIERTA is widely regarded as synonymous with long-term stability and thermal resistance.

We are committed to live up to this good reputation. BARRIERTA L55 series products are made from clearly specified raw materials and the production and quality of the end product is closely monitored.

BARRIERTA L 55/0-3 series long-term greases offer excellent resistance to high temperature and aggressive media and at the same time compatibility with plastics and elastomers.

The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. BARRIERTA L 55/0-3 are NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The use of BARRIERTA L 55/0-3 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Rolling and plain bearings subject to high temperatures

One of the well-known strengths of the BARRIERTA L 55 series is the products' suitability for the lubrication of bearings and guides operating under extreme temperatures. A low evaporation rate enables longest grease lives and hence longest relubrication intervals.

Typical applications include:

conveyors (load and turn rollers)
kiln cart wheel bearings
calender bearings
fan bearings
chain bearings in film stretching stenters

BARRIERTA L 55/2 is most frequently used for initial and long-term lubrication.

For relubrication softer grades of NLGI class 1 or lower are recommended.

Friction points under the influence of media

BARRIERTA L 55 greases offer exceptionally long service lifetimes even when exposed to any of a large number of aggressive media such as concentrated acids, lyes, organic solvents or gases.

In addition to their resistance to media, BARRIERTA L 55/2 and BARRIERTA L 55/3 offer also good adhesion and a sealing effect, which makes them suitable for application in

valves, fittings and installations e.g. in the chemical industry
pneumatic components
level gauges, e.g. for fuels or chemicals
seals (static, dynamic)
extraction systems

Food-processing and pharmaceutical industries

All BARRIERTA L 55 greases are registered as NSF-H1 and are therefore in compliance with FDA 21 CFR § 178.3570.

The additional certification according to ISO 21469 supports the compliance with the hygienic requirements in your production plant.

White-coloured BARRIERTA L 55 special lubricants can therefore also be used on friction points where incidental contact with food products cannot be ruled out for technical reasons, e.g. in rolling and plain bearings and guides operating under high thermal loads in

automatic baking ovens
cooking or frying lines
conveyor systems

Plastic-plastic friction points

BARRIERTA L 55 greases – irrespective of NLGI grade - are neutral towards the majority of plastic materials. Results of pertinent tests with fluoroelastomers can be found overleaf.

We recommend testing lubricant compatibility with the materials in question prior to series application.

High machine performance and less maintenance required:

At high operating temperatures up to 260 °C,
When exposed to aggressive environmental conditions and water vapor,
Where other lubricants may affect sensitive plastic equipment.

For years, BARRIERTA has been used in many industries and types of equipment:

With specially produced base oil to ensure long-lasting stability,
With numerous approval and reference history for various applications,
Tried and tested with NLGI classes suitable for different applications.
