Caustic Soda flakes, micro pearls

 The anhydrous caustic soda is a white crystal substance. It is a strong corrodent. The caustic soda reacts easily to water and a large amount of heat is liberated during this process. The caustic soda absorbs moisture and carbon dioxide from gases. Packing should be kept closely sealed to protect the product from moisture and the resulting from it solidifying.
The caustic soda looks like white freely flowing and fast dissolving flakes, pearls and micro pearls. They have bulk weight between 0,75 and 1,14 kg/gm3. The caustic soda should be kept in the original hermetically sealed packing in airy and dry places.
Safety precautions should be taken in order to avoid any accidental contact with between caustic soda and water, as well as other chemicals with which it reacts violently, e.g. tri chlorine ethylene, ethylene bi chloride, acetaldehyde, phosphorus, light metals etc.
