Potassium Pyrophosphate descriptions
Potassium pyrophosphate is Water-soluble, colorless crystals; dehydrates below 300°C, melts at 1090°C; Potassium pyrophosphate is used in tin plating, china-clay purification, dyeing, oil-drilling muds, and synthetic rubber production. Potassium pyrophosphate is Also known as normal potassium pyrophosphate; tetrapotassium pyrophosphate.
Potassium Pyrophosphate Applications
Potassium pyrophosphate is mainly used in plating without cyanide and bleaching leather products as stabilizer. Under two special conditions, potassium pyrophosphate must be utilized: first is heavy - dirt deterging in controlling foam; second is cleaning metal surface. Potassium pyrophosphate is also adopted in detergent industry. Our Potassium Pyrophosphate comply with International Quality Standards and their quality and durability are fully guaranteed.
