Aluminum Hydroxide

Aluminum hydroxide (CAS No. 21645-51-2), with the molecular formula Al(OH)3, is an inorganic compound appearing as a fine white crystalline powder. It is amphoteric in nature and is the most widely used halogen-free flame retardant and smoke suppressant globally. When heated, it decomposes endothermically, releasing water vapor, which effectively dilutes combustible gases, cools the material, and forms a protective ceramic-like char layer.

Key Applications

• Flame Retardant Filler
• Polymer Composites
• Adhesives & Sealants
• Construction Materials
• Pharmaceuticals & Cosmetics
• Water Treatment

The main detailed uses of the product

Flame Retardant Filler

Serves as a carbonific agent in intumescent coatings that expand to protect substrates from fire.
Polymer Composites

Serves as the primary raw material for the production of bisphenol-A based epoxy resins and other epoxy polymers. These resins are essential for protective coatings, composites, and electronic materials due to their excellent adhesion and chemical resistance.
Construction Materials

Used in the manufacture of fiber-reinforced composites for aerospace, automotive, and sporting goods, where a balance of strength, stiffness, and resistance to environmental degradation is required.
Pharmaceuticals & Cosmetics

Serves as an extraction solvent in the manufacturing of pharmaceuticals and as a component in tablet coatings.
