Recommendations of use

In pulp production, anhydrous MgSO₄ is used to increase selectivity in oxygen delignification, as well as in peroxide- and oxygen-supported bleaching stages. Magnesium sulphate raises cellulose quality and helps to save process chemicals.

In the chemical industry MgSO₄ anhydrous is used as a very versatile raw material for producing other magnesium compounds. In the construction industry our product is used as a component of Sorel-cement-type mixtures. In the ABS-/EPS- production via emulsion polymerisation the salt is used to coagulate the plastic material. In rayon production, it is used as an ingredient of spinning baths. In the production of magnesium-oxide-based refractories MgSO₄ anhydrous is used for stabilising the green body during the drying and sintering process. As a raw material, it is also used in the production of magnesium silicate. MgSO₄ anhydrous is also applied as a stabilising agent for bleaching agents such as peroxides and perborates, which are commonly used in detergents. The cosmetics industry also uses this product as a raw material.
