Sodium Carbonate

 
Sodium Carbonate
 

Applications: Manufacture of glass is one of the most important uses of sodium carbonate. It is also used as a pH regulator to 

maintain stable alkaline conditions necessary for the action of the majority of photographic film developing agents. It is used 

for  dyeing. It is used in the brick industry as a wetting agent to reduce the amount of water needed to extrude the clay. Also 

used for toothpastes. 

 

Packing: 1 Ton Big Bags. Other packing size and pallets on request only.
