| CAUSTIC SODA Caustic soda of our plant is made by membranes processes, the capacity of which is 200000MT/year.
Product name: Sodium Hydroxide (solid, flakes, &pearl) Popular name: Caustic soda Molecular formula: NaOH Molecular weight: 39.997(according to international atomic weight) Appearance: main body white, allowing slight yellow, gloss. Standard: GB 209-93 Application: mainly used in synthetic fiber, papermaking, organic synthesis, textile, artificial silks, pharmacy and metallurgy. Package: Solid in 250kg net iron drum. Flake and Pearl in 25kg net plastic woven bags lined with PE bag. Notes: solid sodium hydroxide by ion membranes process, stored in a dry storehouse, avoided damage, pollution, moisture, tough with acid, prevented from impact in transporting.
