Description

Phosphoric Acid Tri-n-Amyl Ester is a high-purity organophosphorus compound, specifically a trialkyl phosphate ester. This product serves as a versatile and effective intermediate and functional additive in advanced chemical synthesis and material formulation. It is primarily sought after by manufacturers in the polymer, lubricant, and specialty chemical industries for its role as a plasticizer, flame retardant synergist, and extractant. Our supply ensures consistent quality and reliable global availability for industrial-scale operations.

Application

• Plasticizer and Modifier: Used as a secondary plasticizer and viscosity modifier in PVC, cellulose acetate, and synthetic rubber formulations to improve flexibility and processing.
• Flame Retardant Synergist: Acts as a component in flame-retardant systems for polymers and textiles, often enhancing the efficacy of primary halogenated or phosphorus-based retardants.
• Solvent and Extractant: Employed as a solvent for resins and gums, and as an extractant in hydrometallurgy for the separation of rare earth elements and other metal ions.
• Lubricant Additive: Functions as an extreme pressure (EP) additive and anti-wear agent in synthetic lubricants and hydraulic fluids.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex organophosphorus compounds, including pesticides and pharmaceuticals.
• Stabilizer: Used to stabilize peroxides and other reactive compounds against decomposition.
