Caustic Soda, also known as Sodium Hydroxide, it is one of the most widely used chemicals in the industry. Caustic soda is a solution of Sodium hydroxide (NaOH) in water and by evaporating process turns into solid state (flakes), pure sodium hydroxide is a whitish solid, sold in flakes form. It is a strong base with a wide range of applications in different industries. We produce caustic soda together with chlorine and hydrogen from the electrolysis of salt brine.

Chemical formula

NaOH

Uses

The major users of caustic soda in:

·       Soaps and detergents sectors

·       Water treatment (for the flocculation of heavy metals and acidity control)

·       Inorganic chemicals like paints, glass and ceramics and uses in fuel cell production and cosmetics

·       The paper, pulp and cellulose industries

·       Food industry

·       Oil wells in drilling and production stages

·       Textile sector (as a bleaching agent)

·       Aluminum Production

·       Mineral oils (preparation of greases and fuel additives),

·       Synthesis of the synthetic fiber rayon.

 

Our plant produce caustic soda in three main types:

Caustic Soda Solid (flakes):  Concentration 98.5%
• Caustic Soda liquid:               Concentration 48-50%
• Caustic Soda liquid:               Concentration 32%

For liquid type we can supply any concentration below 50% based on customer request.

Packing:

Caustic Soda flakes: in polyethylene bags of 25, 40 and 50 Kg.

Caustic Soda liquid: In bulk and plastic drums of 25, 40, 50 L, also in plastic cubical of 1 Ton capacity.
