Applications: 

• Flame Retardant and Smoke Suppression Applications: Mg(OH)₂ nanoparticles are widely used as halogen-free flame retardants in polymers, rubbers, and textiles. Upon endothermic decomposition, they release water vapor, which cools the material surface, delays ignition, and dilutes flammable gases. Additionally, they inhibit oxygen from supporting combustion, effectively suppressing smoke and toxic gas formation. Common applications include fire-resistant cables, insulation foams, automotive components, and electronic casings.
• Environmental and Wastewater Treatment: Mg(OH)₂ nanopowder serves as a non-toxic alkali for neutralizing acidic industrial effluents. It is used in wastewater treatment plants to adjust pH levels and precipitate heavy metals. Its high surface area enhances reactivity, making it suitable for flue gas desulfurization (FGD), CO₂ capture, and pollutant remediation in chemical and metallurgical industries.
• Polymer and Composite Enhancement: In polymer matrices such as PP, PE, PVC, and EVA, magnesium hydroxide nanoparticles improve thermal stability, mechanical strength, and fire resistance. Their nanoscale dispersion allows effective performance at lower loadings, preserving the host material’s physical properties. They are increasingly adopted in wire insulation, automotive interiors, and construction composites.
• Pharmaceutical and Healthcare Applications: Mg(OH)₂ nanoparticles are used as active ingredients in antacids and laxatives due to their mild alkalinity and biocompatibility. They also exhibit antimicrobial and anti-inflammatory properties, making them suitable for topical formulations and skin treatments. Their low toxicity supports safe integration into biomedical materials.
• Coatings and Surface Protection: In industrial coatings and paints, magnesium hydroxide nanoparticles enhance corrosion resistance, UV protection, and thermal insulation. They are applied in antibacterial coatings, self-cleaning surfaces, and protective layers for metal and polymer substrates.
