Chemical Corrosion PFPE Grease YBS-1772 Manufacturer JLD High Temperature Perfluoropolyether Grease For Bearings

YBS-1772 perfluoropolyether fluorinated grease is a high-viscosity, long-life grease made from highly chemically stable perfluoropolyether oil (PFPE) as the base oil, thickened with polytetrafluoroethylene (PTFE) powder, and refined with special anti-corrosion additives.


Fluorinated greases are specifically developed for machinery with high maintenance costs or requiring continuous operation. They are a highly efficient, long-life, safe, reliable, and high-performance grease suitable for use under abnormal operating conditions.

High-temperature load capacity: Superior lubrication performance under extreme temperatures; critical load at 150 ℃ can reach 120KG.

Low temperature performance: Excellent low temperature characteristics and viscosity-temperature properties.

Lubrication performance: It has low surface tension and can effectively lubricate the surfaces of friction pairs.

Electrical properties: Good dielectric properties, good insulation properties, dielectric constant of 2.1-2.3, and breakdown voltage up to 30 kV.

Compatibility: Good compatibility with plastics, rubber, and other materials.

  • Evaporation performance: It has low evaporation loss performance.

    Water resistance: After being soaked in water at 25℃-50℃ for 3 hours, there was no change. After being soaked in water at 25℃ for 5 months, there was no change in weight or state, demonstrating excellent water resistance.

    Mechanical stability: It does not decompose under mechanical pressure, maintains a stable state with lubricating oil, and has good rolling stability.

    Economic benefits: Long service life , reduced downtime, lower maintenance costs, and overall cost savings.

Operating Precautions

■ Keep container tightly closed when not in use.
■ Avoid contamination with dust, moisture, or other lubricants.
■ Use only on clean and dry surfaces.
■ Do not mix with hydrocarbon or silicone-based greases unless compatibility is confirmed.
■ Store in a cool, dry, and well-ventilated area away from direct sunlight.
■ Follow standard industrial safety and handling practices.

How To Use

■ Preparing the parts for application: New parts are typically treated with organic rust-preventive oil or lubricated with grease during storage to prevent damage . Before use , new bearings should be inspected for damage and imperfections .
■ Cleaning before use : Corrosion-resistant coatings and rust - proofing for metal surfaces also prevent grease from adhering and causing it to be ejected from the bearing during operation. These coatings can also oxidize and harden , producing debris that can contaminate the grease. A final cleaning of the components must be thorough ; failure to do so may result in a shortened bearing life.
■ Fluorine grease is suitable for use in long-term high-temperature environments, but it also needs to be lubricated regularly, about once every 1-3 months. The amount added can be adjusted according to the length of the lubrication cycle.
