Application

Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In terms of environmental protection, as a flue gas desulfurizer, it can lime as a neutralizer of acid containing wastewater. It is also used as an oil additive to prevent corrosion and desulfurization. In addition, it can also be used in the electronics industry, medicine, sugar refining, as insulation materials and the manufacture of other magnesium salt products.
