Description

Polyphosphoric Acids, C12-18-Alkyl Esters are a class of organophosphorus compounds valued for their multifunctional properties as surfactants, lubricant additives, and corrosion inhibitors. These esters are particularly significant for their ability to modify surface properties and provide anti-wear characteristics in demanding industrial formulations. They are essential for manufacturers in the lubricants, metalworking fluids, and specialty chemical sectors seeking to enhance product performance and stability.

Application

• Primary surfactant and emulsifying agent in industrial cleaning formulations and degreasers.
• Key additive in metalworking fluids and hydraulic oils for its anti-wear and extreme pressure (EP) properties.
• Corrosion inhibitor and anti-rust additive in lubricating greases and protective coatings.
• Dispersant and stabilizer in pigment preparations and other specialty chemical processes.
• Intermediate in the synthesis of more complex organophosphate esters for flame retardants.
• Component in textile processing aids and fiber lubricants.
