Description

Aluminum Magnesium Hydroxide is a high-purity, mixed metal hydroxide compound with significant industrial utility. This material is valued for its synergistic properties derived from its aluminum and magnesium components, offering enhanced performance in key applications. It serves as a critical functional additive and precursor material for industries including polymer manufacturing, flame retardancy, and specialty chemical synthesis.

Application

• As a highly effective flame retardant and smoke suppressant filler in polyvinyl chloride (PVC), polyethylene (PE), and epoxy resins.
• As a key precursor and catalyst support in the synthesis of various mixed metal oxides and hydrotalcites.
• As an acid scavenger and stabilizer in polymer processing to neutralize acidic degradation products.
• In the formulation of halogen-free flame-retardant cables and construction materials.
• As an adsorbent for anions and organic pollutants in water treatment processes.
• In the production of specialty ceramics and glass to modify thermal and chemical properties.
• As a pharmaceutical antacid intermediate (subject to appropriate grade and certification).

Quality Control

Our Aluminum Magnesium Hydroxide is manufactured under a stringent quality management system. Production batches undergo rigorous analytical testing to ensure consistency and meet precise compositional and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, metal ratio, moisture content, and particle size distribution is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. The recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product performance.
