Raw Material Magnesium Hydroxide Fire Retardant in Industrial Grade

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.

Mg(OH)2 Applications

It is more suitable for high -temperature processing plastic requirements. Magnesium hydroxide can be used as a flame retardant such as polyethylene, polypropylene, polyvinyl chloride, triathoolite, unsaturated polyester and other plastic and rubber. It can also be used as a flame retardant for coatings.

Magnesium hydroxide is used as wastewater treatment, desertation of heavy metals, treatment of seal and dyeing wastewater, treatment of arsenic and wastewater, etc.

Magnesium hydroxide used as smoke desulfurization.

Service and Quality

Our natural fine ground Magnesium hydroxide is intensively used as a flame retardant in thermoplastic and elastomer polymer compounds. It can also be used as a component of paints and resins, TPO roofing and flooring applications and in Aluminum Composite panels.
