Description

Sodium Dibutyldithiophosphate is an organophosphorus compound widely used as a high-performance additive and intermediate. Its primary value lies in its excellent properties as an antioxidant, anti-wear agent, and corrosion inhibitor, making it a critical component in advanced formulations. This product is essential for manufacturers in the lubricant, metalworking fluid, and polymer stabilization industries seeking to enhance product durability and performance.

Application

• Lubricant Additive: Functions as a multifunctional anti-wear and extreme pressure (EP) agent in industrial oils and greases.
• Metalworking Fluids: Provides superior lubrication and corrosion protection in cutting, grinding, and drawing fluids.
• Polymer Stabilizer: Acts as an antioxidant and thermal stabilizer in synthetic rubbers and plastics to prevent degradation.
• Corrosion Inhibitor: Used in hydraulic fluids and industrial coolant systems to protect metal surfaces.
• Flotation Agent: Employed as a collector in the mineral processing industry for the separation of sulfide ores.
• Chemical Intermediate: Serves as a key precursor in the synthesis of other specialized organophosphorus compounds.
