It is a potassium phosphate derivative with excellent chelating capabilities and a variety of food and industrial uses.
Technical grade Tetrapotassium Pyrophosphate is used in many industrial applications such as surface Tetrapotassium Pyrophosphate treatment, paint and coatings, boiler descaling, detergent manufacturing, mining of ore and clay, oil drilling, and synthetic rubber production. TKPP also has a higher solubility in water treatment formulations than sodium derivatives. Tetrapotassium Pyrophosphate is used in food applications as an additive in meats, poultry, and seafoods.

Proporties & Usage
Properties: Potassium pyrophosphate is water-soluble, colorless crystals; dehydrates below 300°C, melts at 1090°C; It is used in tin plating, china-clay purification, dyeing, oil-drilling muds, and synthetic rubber production.
Applications: Potassium pyrophosphate is mainly used in plating without cyanide and bleaching leather products as stabilizer. Under two special conditions, it must be utilized: first is heavy - dirt deterging in controlling foam; second is cleaning metal surface. It is also adopted in detergent industry. Our product comply with International Quality Standards and their quality and durability are fully guaranteed. It can also be used as a buffering reagent and stabilizer for hydrogen peroxide, dispersion agent for ceramic, clay, latex and pigments etc. It can be used in food processing of emulsifier, organization, quality improver, improvers chelating agent.
Storage & handling: Keep in cool dry place. Air transportation: arranged as ordinary goods. Harzards Identification & Classifications: N/A
