Product Description
Dioleyl Phosphonate is a phosphorus-based compound used in selected lubricant and industrial additive formulations. It can help improve anti-wear performance and load-carrying capacity, supporting effective lubrication under demanding operating conditions. Depending on the formulation, it may also contribute to friction control, helping reduce wear and support equipment reliability and service life.
In addition to lubricant applications, related phosphorus-based additives are used in certain industrial formulations to support material protection and processing stability. Its suitability for fuel additives or petroleum refining applications should be confirmed through product-specific technical data and application testing.
For optimal performance, the recommended dosage and compatibility should be evaluated according to the intended application, base formulation, and operating conditions.
