BARRIERTA L 55/3 – High-Performance Lubricant for Extreme Conditions

BARRIERTA L 55/3 is Europe’s longest-standing premium brand of high-temperature lubricant, formulated with perfluorinated polyether oil (PFPE). Renowned for its long-term stability and exceptional thermal resistance, BARRIERTA continues to uphold its reputation for superior performance.

The BARRIERTA L 55/3 series is manufactured using strictly controlled raw materials, ensuring consistent quality and reliability. These long-term greases provide outstanding resistance to high temperatures and aggressive media while maintaining compatibility with plastics and elastomers.

BARRIERTA L 55/3 NSF H1 registered and comply with FDA 21 CFR § 178.3570, making it suitable for incidental contact with food products and packaging materials in food-processing, cosmetics, pharmaceutical, and animal feed industries. It's use enhances production reliability, though we recommend conducting a risk assessment, such as HACCP, for added safety assurance.

Applications

High-Temperature Rolling and Plain Bearings

The BARRIERTA L 55/3 is ideal for lubricating bearings and guides that operate under extreme temperatures. With a low evaporation rate, these greases provide extended service life and prolonged relubrication intervals.

Typical applications include:

• Conveyors (load and turn rollers)
• Kiln cart wheel bearings
• Calender bearings
• Fan bearings
• Chain bearings in film-stretching stenters

Lubrication in Aggressive Environments

BARRIERTA L 55/3 grease delivers exceptional longevity even when exposed to harsh substances such as concentrated acids, lyes, organic solvents, and gases. It's superior adhesion and sealing properties make them ideal for:

• Valves, fittings, and installations in the chemical industry
• Pneumatic components
• Level gauges for fuels or chemicals
• Seals (static and dynamic)
• Extraction systems

Food-Processing and Pharmaceutical Applications

As NSF H1-registered lubricants, BARRIERTA L 55/3 complies with FDA 21 CFR § 178.3570. Additionally, certification under ISO 21469 ensures compliance with hygiene standards in production environments. 

Due to their white color and food-grade certification, BARRIERTA L 55/3 lubricant is suitable for friction points where incidental food contact is unavoidable, such as:

• Rolling and plain bearings in automatic baking ovens
• Cooking and frying lines
• Conveyor systems exposed to high thermal loads

Plastic-Plastic Friction Points

Regardless of the NLGI grade, BARRIERTA L 55/3 grease is generally compatible with most plastics. We recommend performing compatibility tests before large-scale application, especially with fluoroelastomers.

Application Guidelines

Before applying BARRIERTA L 55/3, friction points must be free from oil, grease, perspiration, and contaminants.
