Oleonuezhenide is primarily used in the formulation of specialty lubricants and greases due to its excellent thermal stability and resistance to oxidation. It performs effectively in high-temperature environments, making it suitable for industrial machinery and automotive applications where long-lasting lubrication is required. Additionally, it serves as a key additive in metalworking fluids, enhancing tool life and surface finish during machining processes. Its biodegradable nature also makes it a favorable choice in environmentally sensitive applications, including marine and agricultural equipment lubricants.
