Improving The Heat Resistance Of Lithium Grease
Lubrizol® 5370C is a boron ester grease additive that improves the heat resistance of lithium 12-hydroxystearate greases. To be effective, grease must remain in the places where it’s needed, delivering superior performance under a wide range of conditions. Grease that liquefies or “bleeds out” under high temperatures can lead to uneven lubrication of equipment, resulting in wear, downtime and costly repairs.
Designed for use in all 12-hydroxystearic acid-based lithium soap greases, Lubrizol 5370C grease additive provides significant benefits to manufacturers and end-users.
The Challenges
Grease producers today face the challenges of time, capacity and variation. Manufacturing lithium complex grease using conventional complexing acids requires a lengthy processing cycle, which limits the quantity of lithium complex greases that can be produced. And any batch to batch variation in the process, particularly in terms of dropping point, can be costly and time consuming.
When process variations result in batches with a low dropping point, the product cannot be sold as a complex grease. Instead, the batch must be reworked or discarded.
The Solution – Lubrizol 5370C
It’s a fact that simple lithium soaps are faster to manufacture than complex soaps. Lubrizol 5370C bridges the gap between lithium complex and lithium simple soap greases by increasing the 12-hydroxystearic acid-based soap’s heat resistance to the level of a complex grease. The end result is a high dropping point lithium grease with the process cycle times of a simple soap, a possible 40% time savings over conventional manufacturing processes
