Manufacturing Process

The manufacturing of this product at Unipar takes place in the Cubatão and Bahía Blanca plants. In Brazil, commercial Liquid Caustic Soda is produced in a type of electrolytic cell where brine flows from one compartment to the other through porous layer (diaphragm). In Argentina, there are two electrolysis cell units: one using the mercury cathode technology (Rayon liquid soda) and the other one using the electrolyzer technology with a two-pole membrane (Membrane liquid soda).
