Uses Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In environmental protection, it can be used as flue gas desulfurization agent, being able to replace the caustic soda and lime as acid-containing waste water neutralizer. It can also used as oil additive with anti-corrosion and desulfurization effect. In addition, it can also be used for the electronics industry, medicine, sugar refining, for insulation materials and the manufacture of other magnesium salt products.
One important application of Magnesium Hydroxide is the use of the material in the pharmaceutical industry, for example as antacid to neutralize stomach acids and as laxative.
The largest industrial application of Magnesium Hydroxide is flame retardants for articles such as roofing, isolation materials, plastic articles and coatings. The mechanism of flame retardancy is based on the endothermic decomposition of the material into MgO and H2O. This reaction adsorbs heat, which delays ignition of the associated substance. The water that is released dilutes combustible gases and inhibits oxygen from aiding the combustion.
