Sodium Hexameta Phosphate Anhydrous Industrial Grade

Sodium Hexameta Phosphate (SHMP) is a mixture of polymeric Metaphosphates of which the Hexamer is one. It is prepared by heating Monosodium Orthophosphate until it starts melting and the process is followed by rapid cooling.


  Sodium Hexameta Phosphate is widely used in water softeners & detergents
  Sodium Hexameta Phosphate is also used in leather tanning, dyeing, laundry work and textile processing
  SHMP is used in process called 'threshold treatment' which is softening of industrial water supplies
  SHMP is used as a sequestrant and as a food additive
