Category of sodium hydroxide (caustic soda):

Sodium hydroxide tech grade: Solid IS-IT I II (ion-exchange membrane caustic soda flakes and pearls). Liquid IL-IT I II (ion-exchange membrane caustic soda solution).

Sodium hydroxide for chemical fiber: Solid FS I, liquid FL I II III.

Sodium hydroxide high pure: Solid HS I, Liquid HL I II III.

Sodium hydroxide food grade.

Characters:

Sodium hydroxide solid is mainly white flakes (granular). Molecular formula is NaOH and density is 2.13 with strong alkaline, hygroscopic, strongly causticity to skin and clothing. It can easily produce sodium carbonate via absorbing water in air so it must be warehoused in dry and clean sites with fine closed packages.

Sodium hydroxide liquid is colorless and transparent solution with strong alkaline, dense causticity to skin, textile and paper.

Packing: 25kg plastic weaving bags with inner film or flexibags for solid products and Tank for solutions.

Application: Sodium hydroxide is an important raw chemical materials. It mainly find uses in food industry, oil extraction, paper making, artificial fiber, textile, printing and dyeing, sewage treatment, non-ferrous metal metallurgy, chemical fertilizer, organic synthesis, pharmaceutical, delay chemicals, fine chemical, plastic and water treatment, etc.
