Flame Retardant Magnesium Hydroxide

Physical Property                                 

Name: Magnesium Hydroxide

Commonly known as: Magnesium Hydroxide (High-Purity Flame Retardant Grade); Caustic Magnesite

Molecular formula: Mg(OH)2

Molecular weight: 58.320

Appearance: White amorphous powder or colorless hexagonal column crystals.

Magnesium Hydroxide are magnesium hydroxide produced by chemical synthesis, with high purity and uniform particle size distribution. At the same time, they have excellent flame retardant and smoke suppression functions. They are an excellent choice for manufacturing green halogen-free and environment-friendly flame retardant materials. The thermal decomposition of the product can absorb a large amount of heat on surface of combustor and release a large amount of water to dilute oxygen. The Magnesium Oxide generated after decomposion is attached to surface of combustor to further isolate the transfer of oxygen and heat, so as to prevent combustion. Compared with aluminum hydroxide, magnesium hydroxide has the advantages of high decomposition and absorption heat, good thermal stability and low relative hardness.



1. Widely used in rubber, chemicals, building materials, plastics, electronics, unsaturated polyester, paint, coatings and other polymer materials.
2. Mainly used as flame retardants, acid wastewater treatment agents, heavy metal removal agents, and flue gas desulfurization agents in the field of environmental protection.
3. As an oil additive, it has anti-corrosion and desulfurization effects.
4. It is added to polyethylene, polypropylene, polystyrene and Acrylonitrile butadiene styrene as flame retardant or flame retardant filler, which has good flame retardant and smoke suppression effects,
5. Especially for the flame retardancy, smoke suppression and anti-static of coating cloth for mine air duct, PVC whole core conveyor belt, flame retardant aluminum plastic plate, flame retardant tarpaulin, PVC wire and cable material, mine cable sheath, cable accessories, it can replace Aluminium hydroxide, with excellent flame retardant effect.
