What Are Caustic Soda Flakes?

Caustic Soda Flakes, or Sodium Hydroxide (NaOH), are essential alkaline chemicals widely used across various industries. Available in four distinct grades—Industrial, Food, Technical, and Pharmaceutical—each grade caters to different application requirements. The flakes’ crystalline form offers excellent handling, rapid dissolution, and precise dosing characteristics.
