Caustic Soda Flakes (Sodium Hydroxide)
Original price was: $ 1.65.$ 1.55Current price is: $ 1.55.
Caustic Soda Flakes, also known as Sodium Hydroxide Flakes (NaOH), are a highly alkaline, white, solid substance that is crystalline and flaky in form. Produced by evaporating aqueous sodium hydroxide solutions, these flakes are highly soluble in water and exhibit strong corrosive properties. Caustic Soda Flakes are widely used in a variety of industrial, chemical, and manufacturing processes due to their strong alkalinity, ability to saponify fats, and effectiveness in pH adjustment. Their high purity and ease of handling in flake form make them suitable for use in chemical synthesis, pulp and paper production, water treatment, and detergent manufacturing.
