Description
CAUSTIC SODA
Sodium hydroxide, otherwise called Caustic Soda, is an inorganic compound with chemical formula NaOH. It is called caustic soda because it is highly corrosive in nature. It is available in many forms in the industry, and the most common forms are caustic soda flakes and caustic soda pearls. This product has several industrial applications but it is highly reactive, so it has to be used carefully lest, it can cause skin irritation.
Caustic Soda is a strong base with a wide range of applications in different industries.
Worldwide, the major users of caustic soda are the aluminum industry, pulp & paper and the chemical industry. The main applications are water treatment and water purification, as cleaning agent, or a wide range of uses in chemical industry like starch production or for the desulphurization in the petrochemical industry.
