Sodium Hydroxide DESCRIPTION Anhydrous Caustic Soda is produced by multi-stage evaporation process and transformed into the solid state either as micro spherical particles called prills or as caustic soda solid of white color. Prills being denser than flakes, occupy for the same weight of Caustic. This Permits Optimum utilization of storage facilities and minimal transport cost.
