Klüber BARRIERTA L 55/3 High-temperature long-term grease 10Kg

BARRIERTA L 55/3 high temperature grease 10 kg hobbock steel high-performance lubricant based on perfluoropolyether oil (PFPE)

• operating temperature range up to 260 ° C
• protects against aggressive chemicals and vapors
• for use with sensitive plastic materials.

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 high-temperature 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.
