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.
