Applications of Magnesium hydroxide

Magnesium hydroxide (CAS 1309-42-2) is an inorganic mineral powder widely used as a functional filler and halogen-free flame retardant in polymer, environmental-protection and coating formulations. Its chemical properties make it particularly suitable for flame-retardant composites, waste-water treatment, and selected high-performance environmental-friendly systems.

Polymer & Rubber Flame Retardant Fillers

Magnesium hydroxide is commonly used in the production of halogen-free flame-retardant polymers for plastic and rubber products. Its mineral structure can support low smoke emission, non-toxic performance, and good thermal stability, making it suitable for polymer material applications.

Typical application areas include:

• Polyethylene and polypropylene composites

• Rubber insulation materials

• Wire and cable compounds

• Building plastic profiles

• Household plastic products

High-Performance Coatings & Construction Materials

Magnesium hydroxide can be used in coating systems designed for low-smoke, non-toxic, and environmental-friendly architectural coatings. Magnesium-hydroxide-based coating formulations may provide a useful balance of filling performance and fire-resistant property, including acid-neutralizing capacity, moisture resistance, and corrosion inhibition.

It is particularly suitable for formulations where halogen-free feature, good dispersion, and stable filling performance are required.

Waste-Water Treatment & Flue-Gas Desulfurization

Magnesium hydroxide is also used as an acid-neutralizing component in water treatment and flue-gas desulfurization systems. These systems are applied in environmental-protection projects and applications requiring mild and efficient neutralizing performance.

Typical applications include:

• Industrial wastewater neutralization treatment

• Flue-gas desulfurization for power plants

• Heavy-metal ion precipitation

• Municipal sewage adjustment

Building Insulation & Composite Materials

Magnesium-hydroxide-modified systems can be used in building insulation and composite applications, particularly where fire safety performance and long-term environmental stability are important performance considerations.

The final performance of Magnesium hydroxide in any compound or treatment system depends on the complete formulation, particle size, processing conditions, dosage, and intended end use. Customers should evaluate product suitability according to their specific formulation and application requirements.
