Performance Advantages
Why PAG for Grease Manufacturing
Wide thickener compatibility
PAG base oils are compatible with all major grease thickeners (lithium complex, calcium sulfonate, polyurea, aluminium complex, clay), giving formulators maximum flexibility.
High dropping point
PAG-based greases maintain structural stability at elevated temperatures, extending the operating range of the finished grease beyond what mineral oil-based greases can achieve.
Superior low-temperature performance
PAG greases maintain pumpability and consistency at temperatures where mineral oil greases become hard or unworkable (down to −40°C and below).
Enhanced film strength
The high VI and inherent film strength of PAGs improve the load-carrying capacity of the finished grease, particularly in slow-speed, high-load bearing applications.
Application Segments
Sub-Segments
Lithium Complex
The most common multipurpose grease; PAG base oils improve high-temperature performance and water resistance.
