Chlorine and Caustic Soda are produced from salt and water. An electrochemical process separates chlorine from the salt and combines the remaining sodium with hydrogen and oxygen from the water to produce sodium hydroxide, or caustic soda.HOW IS IT SHIPPED ?
Caustic Soda Flakes, Pellets, Pearls & Caustic Soda Solid (NaOH) used in the following processes are shipped in bags, boxes and in covered hoppers. Handling is manual, by forklift or unloaded pnuematically from the hoppers.WHAT IS IT USED FOR ?
This table is not comphrensive but indicates some of the many uses of Caustic-Soda.

Liquid caustic soda is normally stored in mild steel tanks. It is generally non-corrosive to mild steel at ambient temperature, although it does pick up a very small amount of iron. In uses where iron impurity is undesirable, stainless steel tanks should be used. Rubber-lined tanks may also be used at ambient temperature, as are plastic tanks such as PVC, polyethylene, and polypropylene.
Liquid Caustic Soda with 48% to 50% NaOH can cause very rapidly serious burns to the skin and permanent injury to the eyes. Caustic Soda should always be handled with care by thoroughly trained personnel wearing the appropriate protective clothing and equipment. Liquid Caustic Soda is classified as hazardous chemical.
