Product Overview
Industrial Grade Tetrasodium Pyrophosphate (TSPP), with the chemical formula Na₄P₂O₇, is a multifunctional inorganic phosphate designed for industrial and detergent applications where strong buffering capacity, chelation, and dispersion performance are required. Supplied as a white, free-flowing crystalline powder, industrial-grade TSPP is widely used in detergent manufacturing, industrial cleaning formulations, boiler water treatment, metal surface processing, and related industrial systems.
This industrial-grade product focuses on functional efficiency and formulation performance rather than food or pharmaceutical compliance, making it suitable for large-scale industrial use.
Key Benefits (Industrial Grade)
· Strong chelating ability for calcium and magnesium ions, improving water-softening efficiency
· Excellent alkaline buffering to enhance cleaning and degreasing performance
· Effective dispersion of pigments, slurries, and mineral particles
· Improves formulation stability and processing consistency
· Helps prevent boiler scale formation and improves heat-exchange efficiency
· Reliable and consistent quality for continuous industrial operation
Customer Focus Points
· Need an industrial phosphate for detergents and cleaners → TSPP provides strong builder and buffering performance
· Require effective water softening → Chelates Ca²⁺/Mg²⁺ to improve cleaning efficiency
· Concerned about dispersion stability → Maintains uniform suspension and reduces settling
· Operating under alkaline conditions → Provides stable pH buffering
· Moisture sensitivity during storage → Supplied with moisture-protective packaging
