Description
Caustic Soda Flakes are a white, odorless, and highly corrosive solid form of Sodium Hydroxide (NaOH).
Produced by evaporating caustic soda liquid, these flakes are widely used due to their high purity, strong alkalinity, and reactivity.
Commonly applied across textiles, pulp & paper, soap, and petrochemical industries.
