Caustic Soda Flakes & Pearls 99% for Metallurgy and Metal Processing

Product Description

NaOH

Industrial grade Caustic Soda is available in flake and pearl forms, appearing as white solid. Refined by ion-exchange membrane process, it has a NaOH content of ≥99%, featuring high purity, low impurity, excellent solubility, strong alkalinity and stable performance.

This product is highly soluble in water with heat release during dissolution. It possesses strong alkalinity and corrosiveness, which can effectively neutralize acidic substances, adjust the pH value of systems, and provide excellent saponification, degreasing and cleaning effects.

Impurity indexes including sodium carbonate, sodium chloride and iron ions are strictly controlled, much lower than conventional standards. It produces few by-products during application and will not adversely affect production processes and finished product quality, making it suitable for industrial production in textile, paper making, water treatment, chemical synthesis, metallurgy, leather, electroplating, detergent manufacturing and other fields.

The product is packed in 25kg double-layer moisture-proof packages with good sealing performance to effectively prevent moisture and caking. It is classified as Class 8 corrosive dangerous goods with UN No. 1823. With stable physical and chemical properties, it can be stored for a long time in dry and sealed environment, serving as an indispensable basic inorganic strong alkali raw material in modern industrial production.
