Applications:
Magnesium Hydroxide (Mg(OH)₂) nanoparticles are used across multiple industries:
Flame Retardant and Smoke Suppression: Mg(OH)₂ nanoparticles act as halogen-free flame retardants in polymers, rubbers, and textiles. During endothermic decomposition, they release water vapor, cooling surfaces, delaying ignition, and diluting flammable gases. They also restrict oxygen availability, 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 serves as a non-toxic alkali for neutralizing acidic industrial effluents. It adjusts pH levels and precipitates heavy metals in wastewater treatment. Its high surface area makes it suitable for flue gas desulfurization (FGD), CO₂ capture, and pollutant remediation in chemical and metallurgical industries.
Polymer and Composite Enhancement: In polymers such as PP, PE, PVC, and EVA, magnesium hydroxide nanoparticles improve thermal stability, mechanical strength, and fire resistance. Nanoscale dispersion enables effective performance at lower loadings, preserving the host material’s physical properties. Applications include wire insulation, automotive interiors, and construction composites.
Pharmaceutical and Healthcare Applications: Mg(OH)₂ nanoparticles are used in antacids and laxatives due to mild alkalinity and biocompatibility. They also exhibit antimicrobial and anti-inflammatory properties, suitable for topical formulations and skin treatments. Low toxicity allows safe integration into biomedical materials.
Coatings and Surface Protection: In coatings and paints, Mg(OH)₂ 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.
