Short Description:

Anhydrous sodium sulfate is a sodium sulphate mineral without crystalline water. It belongs to monoclinic crystal system, whose aggregate looks like light yellow to colorless dense block or crust. It has the appearance of small transparent granular crystals, and is odorless, bitter-tasting and hygroscopic. Anhydrous sodium sulphate is insoluble in strong acids, aluminum, or magnesium.

It is easily hydrated in humid air and turns into water-containing powder covering the surface.

Manufacturing Process of Modified Sodium Sulphate:

This product produced with high purity sodium sulphate solution, coated the surface with special wet processing technology, they spray drying and become special particle size anhydrous sodium sulfate powder.


      1. 1.It has a refractive index of 1.484, similar to most of the synthetic resin, which can greatly improve the optical property of the end-use products.
      2. 2.With special wet processing surface treatment, the powder has high activation grade, low oil absorption, good dispersion and good compatibility with various resin. It can give the final products good mechanical property and improve the filling rate.
      3. 3.Its high L value can give the final products high gloss and good brightness.
      4. 4.Its unique surface treatment formulation can avoid crystal precipitation of the end-use products.

1.Filler for plastic transparent filler masterbatch and modified plastics.
2.Filler for synthetic detergents.
3.Used as a cooking agent in the manufacture of sulphate pulp in paper making.
4.Used to replace soda ashin glass industry.
5.Raw material for manufacturing sodium sulfide, sodium silicate and other chemical products.
6.Used to blend vinylon spinning coagulation textile industry.
7.In the printing and dyeing industry, it is used as dyeing aid and pretreatment agent.
8.In construction projects, it is used as cement admixture, early strength agent, antifreeze agent and grinding aid in cement processing.
9.Used in synthetic fiber, tanning, non-ferrous metallurgy, porcelain enamel, soap, feed additives, etc.
Packing: 25kg/Plastic woven bag (lined with polyethylene).
