Pure anhydrous sodium hydroxide is white translucent, crystalline solid. It is strongly alkaline aqueous solution with alkali all perforating. It is widely used in aluminum smelting, refining tungsten, paper and rayon and soap manufacturing, the production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration system of metallic sodium, water electrolysis, as well as inorganic salt production, preparation of borax, chromium salt, potassium permanganate, phosphate, etc.

We take great efforts to make sure that our packing is being properly managed and controlled. Our caustic soda flakes are packed with PE bags with PP woven bags outside, while caustic soda pearls are packed with thick PE bags with PP woven bags outside.
