Sodium hydroxide may occur in two forms. The first one is a solution, also known as sodium lye, while the second one is the solid form - flakes, prills or microprills of caustic soda.
PCC Group produces sodium hydroxide in the form of sodium lye by using a modern membrane installation (read more about membrane electrolysis) . The membrane process is distinguishable from other procedures for two reasons. It is not only more environmentally friendly, as it has no impact on the natural environment and does not cause contamination by heavy metals (contrary to the mercury method), but it is also more energy-efficient.
Caustic soda in flakes constitutes an alternative to sodium hydroxide in prills and granules. The advantage of caustic soda in flakes over granules is its significantly faster water solubility. Sodium hydroxide in flakes produced at PCC Rokita is delivered to over 100 countries worldwide. Many international companies appreciate the quality of this product. Customers choosing flakes produced by PCC Rokita know that this product dissolves into the form of sodium lye faster and more efficiently than in case of prills and microprills offered by the competition. Note also that this process causes strong exothermic reaction (heat release), which generates a safety risk, when uncontrolled.
An additional advantage of caustic soda in flakes is its attractive price. After closing many production plants in Europe, the availability of prills significantly decreased. Therefore, the prices of caustic soda in granules substantially increased.
From the economic perspective, caustic soda in flakes offered by PCC Group is much more efficient than caustic soda in prills for all buyers that want to use it in the form of a solution. The number of clients choosing caustic soda in flakes is increasing, as PCC Group, being the manufacturer of chemicals, guarantees a constant supply of the product at competitive prices.
