Product overview

Aluminium hydroxide, with the chemical formula Al(OH)₃, is a white, odorless powder naturally found in minerals like gibbsite or bauxite.

Structurally, it consists of aluminum atoms bonded to hydroxyl (OH⁻) groups, forming a layered crystalline structure.

Applications

1. Flame Retardants in Plastics and Polymers

Electrical cables: Insulation coatings in wires and cables (e.g., PVC-based materials).

Building materials: Fire-resistant panels, carpets, and synthetic rubber.

Automotive parts: Interior components like dashboards and seat foam.

2. Pharmaceuticals and Healthcare

Antacids: Neutralizes stomach acid in over-the-counter medications (e.g., Maalox, Gaviscon).

Vaccine adjuvants: Enhances immune response in some vaccines (e.g., hepatitis B and HPV vaccines).

Dental products: Used in toothpaste as a mild abrasive to remove plaque.
