Applications
Flame Retardant and Smoke Suppression Applications: Mg(OH)₂ nanoparticles are widely used as halogen-free flame retardants in polymers, rubbers, and textiles. During endothermic decomposition, they release water vapor, cooling material surfaces, delaying ignition, and diluting flammable gases. They also reduce oxygen availability, effectively suppressing smoke and toxic gas formation. Common uses include fire-resistant cables, insulation foams, automotive components, and electronic casings.
Environmental and Wastewater Treatment: Mg(OH)₂ nanopowder functions as a non-toxic alkali for neutralizing acidic industrial effluents. It is applied in wastewater treatment to adjust pH and precipitate heavy metals. Its high surface area increases reactivity, making it effective 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 enhance thermal stability, mechanical strength, and fire resistance. Their nanoscale dispersion enables effective performance at lower loadings, preserving material properties. They are used in wire insulation, automotive interiors, and construction composites.
Pharmaceutical and Healthcare Applications: Mg(OH)₂ nanoparticles serve 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 use in biomedical materials.
Coatings and Surface Protection: In industrial coatings and paints, magnesium hydroxide nanoparticles improve corrosion resistance, UV protection, and thermal insulation. They are used in antibacterial coatings, self-cleaning surfaces, and protective layers for metal and polymer substrates.
