Sodium Tetra Poly Phosphate is a specialized inorganic phosphate salt typically supplied as a Technical Grade white powder or granules. It belongs to the family of condensed phosphates, offering a high sequestration capacity for divalent metal ions in aqueous systems.

This chemical is particularly effective as a deflocculant and water softener in industrial applications where high mineral content is present. Its molecular chain length provides a balanced performance between the shorter pyrophosphates and longer hexametaphosphates, ensuring stable pH control.

In the detergent and cleaning sector, it serves as a high-performance builder, preventing the redeposition of soil onto surfaces and enhancing the efficiency of surfactants. Its ability to maintain mineral solubility makes it a preferred choice for specialized boiler water treatment and ceramic production.

Sodium Tetra Poly Phosphate

  • Water Conditioning: Used to soften industrial water and prevent scale formation in pipelines and heat exchangers by sequestering calcium and magnesium.
  • Cleaning Formulations: Acts as a builder in heavy-duty industrial cleaners to improve soil suspension and detergent efficiency in hard water.
  • Ceramics and Clay: Functions as a dispersing agent to reduce the viscosity of clay slips and ceramic glazes for better processing.

Generally considered a Low Hazard substance. May cause mild eye or skin irritation; wear Protective Gloves and Safety Goggles. Store in a Cool, Dry Place to prevent caking.
