Product: Caustic Soda Flakes (NaOH)

CAS No.: 1310-73-2
Hazard Class: 8 (Corrosive)
UN No.: 1823
Appearance: White flaky solid

Description: Caustic soda flakes are produced through the evaporation of sodium hydroxide solution, typically manufactured via chlor-alkali electrolysis process. This highly versatile alkali is widely used in pulp/paper production (kraft process), aluminum refining (Bayer process), soap manufacturing (saponification), and pH adjustment in water treatment. With 99% purity, it rapidly absorbs moisture and CO₂ from air, requiring airtight packaging.
