Pelletized Caustic Soda (Sodium Hydroxide Pellets, NaOH), a high - purity granular form of caustic soda, features a uniform pellet size (2 - 4 mm) for easy handling and precise dosing. Manufactured through advanced extrusion and drying processes, our pellets offer a minimum purity of 99.5% (NaOH), with low iron (Fe ≤ 0.001%) and carbonate (Na₂CO₃ ≤ 0.5%) content. The free - flowing granular structure minimizes dust generation, enhancing safety and operational efficiency in industrial applications.
Key Properties:
Melting Point: 318°C | Bulk Density: 1.4 - 1.5 g/cm³
Solubility: 109 g/100 mL (20°C) | pH: 14 (1% solution)
Hygroscopicity: Rapidly absorbs moisture from air – requires airtight storage.
Applications:
Chemical Industry: Catalyst in esterification and saponification reactions.
Petrochemicals: Desulfurization in natural gas and petroleum refining.
