Magnesium Hydroxide (Mg(OH)₂) Nanopowder (99.9+% Purity, ~100 nm) is a high-purity inorganic nanomaterial designed for multifunctional industrial, environmental, and biomedical applications. With a controlled nanoscale particle size and excellent chemical stability, this material provides efficient performance in systems requiring thermal regulation, pH control, and surface protection.
At elevated temperatures, magnesium hydroxide undergoes an endothermic decomposition process, absorbing heat and releasing water molecules. This behavior makes it particularly effective in fire-resistant formulations while maintaining a non-toxic and environmentally friendly profile. Its high specific surface area further enhances reactivity and dispersion, enabling improved efficiency at lower loadings across various formulations.
Applications
Flame Retardancy and Smoke Reduction
Magnesium hydroxide nanopowder is widely employed as a halogen-free fire-retardant additive in polymers, elastomers, and textiles. Through heat absorption and water vapor release, it delays ignition, reduces flame spread, and limits the formation of smoke and hazardous gases. Typical uses include fire-resistant cables, electronic housings, automotive parts, and insulation materials.
Environmental Protection and Wastewater Processing
This nanopowder functions as a safe alkaline agent for neutralizing acidic waste streams and facilitating heavy-metal precipitation. Its enhanced surface activity supports applications in wastewater treatment, flue gas desulfurization, carbon capture, and remediation processes within chemical and metallurgical industries.
Polymer and Composite Performance Enhancement
In thermoplastics such as polypropylene, polyethylene, PVC, and EVA, magnesium hydroxide nanoparticles improve thermal resistance, mechanical durability, and flame-retardant behavior. Their nanoscale dispersion allows effective reinforcement while preserving flexibility and processability in construction, automotive, and electrical insulation products.
Pharmaceutical and Healthcare Uses
Owing to its biocompatibility and mild alkalinity, magnesium hydroxide is utilized in pharmaceutical formulations including antacids and laxatives. At the nanoscale, it also exhibits antimicrobial and anti-inflammatory properties, supporting its use in topical applications and advanced biomedical materials.
Coatings and Surface Engineering
In protective coatings and paints, magnesium hydroxide nanoparticles enhance resistance to corrosion, UV exposure, and thermal stress. They are incorporated into antibacterial coatings, functional surfaces, and protective layers for metal and polymer substrates.
