Caustic Soda
Caustic soda flakes are highly hygroscopic and soluble in water and are used in a lot of different industries. The purity of this product is min %99. Sodium hydroxide (NaOH), also known as lye and caustic soda, is an inorganic compound. And it is produced from soda lye in from liquid form (membrane electrolysis).
It is a white solid and highly caustic metallic base and alkali salt which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations.
Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water. Sodium hydroxide is soluble in water, ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air.
Application
This petroleum products are used in food Preparation, milk Processing Industry, Canning beverage, sugar, edible oil, metal industry, manufacture of glass, zinc & electroplating, battery industry, the pharmaceutical industry consuming fatty, leather & textile industry, dyeing industry, paper industry, Soap making, aluminum etching and so on.
It is packed with 25 kg thick PP/PE bags and big bag (1000 Kg each).
