Caustic Soda

Caustic Soda or Lye is known chemically as sodium hydroxide. It is called caustic soda because of its burning or caustic effect on the skin. It is one of the basic raw materials of the great alkali industry which, in itself, is one of the most important parts of the chemical industry.
Caustic soda is produced commercially in either of two ways, the electrolysis of brine or the Soda-Lime Process. Pure caustic soda is a white solid that is very soluble in water. It is deliquescent, absorbing water from the air and dissolving in it. In this way, it is known as caustic soda liquor and is a colorless or grey, syrupy liquid with a slight characteristic odor.
Caustic Soda Liquid is a highly reactive material which reacts rapidly with carbon dioxide. Although it is stable chemical, it starts chemical reaction due to temperature changes. The heat causes the product to become unstable and reactions to start and in case of severe heat shock, it can cause explosion. Liquid Caustic Soda is highly corrosive and reacts easily with metals such as Aluminum, Magnesium, Zinc, Chromium, Bronze, Copper and Brass.
Caustic Soda flakes are flakes in white color which are hygroscopic and soluble in water. Caustic soda flakes are obtained by evaporating of qualified liquid caustic soda which is produced with membrane technology.

PETROFRICK supplies both types of Sodium Hydroxide:
1. Liquid
2. Flakes
