CHARACTERISTICS, APPLICATIONS, AND BENEFITS OF HIGH-TEMPERATURE GREASES

High temperature greases (HTGs) are used in industrial setups to reduce friction and wear.Several industries have a working environment where upper operating temperatures exceed the limits of conventional, lithium-thickened greases. HTGs allow the preservation of the lubricant film at high temperatures to provide the viscosity required for operating machinery. These greases are applied when the temperature at the bearing surfaces is higher than 500°C and the chemical resistance of a regular lubricant falls short. This requires high-temperature grease to have certain characteristics, such as chemical resistance, low viscosity, mobility, and proper packaging. High-temperature greases have a wide range of applications and come in diverse forms depending on the industrial sector. 

Applications of high temperature greases: 

• High-temperature greases are often used on automotive parts that operate at extreme temperatures like cylinder heads, crankshafts, pistons and camshafts as well as bearings and seals. 
• In welding processes, high-temperature greases are also widely used for their extreme heat resistance.
• In industrial applications, high temperature greases are used for gears, bearings, valves and other rotating parts where they are exposed to extreme heat. Additionally, on components of an engine block. 
• High temperature grease is used in oil fields where drilling rigs are mobile and need to be able to operate at high temperatures for extended periods of time to reduce wear.  

Benefits of using high temperature grease: 

• High-temperature greases can withstand extreme temperatures and are considered a more effective alternative to regular lubricants in industrial, automotive, and metal-working processes. 
• High-temperature greases provide exceptional thermal and mechanical stability over regular lubricants and ensure prolonged product integrity across a wide range of operating temperatures, thus reducing maintenance and relubrication intervals.
• High-temperature greases are excellent at protecting against wear in industrial environments.
• High-temperature greases provide enhanced protection in applications with higher potential for exposure and contamination.
