Key Features and Advantages ofHigh-Temperature Grease

Exceptional Heat Resistance andLong-Lasting Lubrication

High-temperature grease is specificallyformulated to perform in extreme heat conditions, maintaining stability withoutoxidation or degradation. It ensures long-term operation of critical machineryand exhibits excellent low-temperature fluidity, making it ideal for bearings,chains, and sliding gears exposed to extreme temperatures.

Superior Chemical Stability

Synthetic-based high-temperature grease isoften fortified with high concentrations of polytetrafluoroethylene (PTFE)particles, enhancing its thermal stability, pressure resistance, and oxidationresistance. Additionally, it demonstrates excellent thixotropic properties: itflows when external force is applied and returns to its original state when theforce is removed. This minimizes grease loss and extends lubricationeffectiveness.

Key Materials and Their Applications

Silicone-based lubricants (SiO₂) are widelyused due to their high oxidation resistance and no drop point, making themsuitable for prolonged high-temperature applications. Boron nitride (BN), acutting-edge solid lubricant and thickening agent, boasts a high melting pointand superior thermal resistance, making it a crucial component in aerospace anddefense industries. Bearings lubricated with boron nitride grease can operatefor over 2000 hours at 121°C and 10,000 rpm.

Applications in High-Tech Industries

High-temperature grease is extensively usedin aerospace, nuclear energy, and automotive industries, particularly inmissile and rocket propulsion systems and extreme industrial environments.Perfluoropolyether (PFPE)-thickened greases provide unmatched chemicalinertness, thermal stability, and non-flammability, delivering highly reliablelubrication for equipment operating under the harshest conditions.
