4. Ceramics & Glass
  • Application: Used in the production of ceramic glazes, spark plug insulators, and glass formulations to control viscosity and improve clarity.

5. Water Treatment
  • Acts as a flocculant or coagulant aid, especially when transformed to alum (aluminium sulfate) or polyaluminium chloride.

6. Paper Industry
  • Acts as a retention aid, filler, and sizing agent.

  • Enhances brightness, opacity, and printability of high-grade paper.

7. Cosmetics & Personal Care
  • Used in deodorants, toothpastes, and skin creams as a pH buffer, opacifying agent, and abrasive.

Aluminium Hydroxide [Al(OH)₃] is a white, non-abrasive, fine powder with amphoteric properties—meaning it can react with both acids and bases. It finds widespread use across industries due to its flame retardant, filler, and antacid properties.

Industrial Uses & Applications of Aluminium Hydroxide 1. Flame Retardant in Plastics & Polymers
  • Application: Used in thermoplastics, thermosets, elastomers, and coatings.

  • Function: Releases water upon decomposition (at ~200°C), which cools the material and suppresses smoke and flames.

  • Industries: Electrical insulation, cable jacketing, carpet backing, and roofing materials.

2. Filler in Rubber & Paints
  • Rubber Industry: Acts as a reinforcing filler in rubber products, enhancing fire resistance and mechanical strength.

  • Paints & Coatings: Improves opacity, brightness, and flame retardancy in specialty coatings.

3. Pharmaceutical & Medical
  • Antacid: Neutralizes excess stomach acid in over-the-counter formulations (e.g., tablets, syrups).

  • Vaccine Adjuvant: Used to enhance immune response in vaccines like hepatitis A, B, etc.

4. Ceramics & Glass
  • Application: Used in the production of ceramic glazes, spark plug insulators, and glass formulations to control viscosity and improve clarity.

5. Water Treatment
  • Acts as a flocculant or coagulant aid, especially when transformed to alum (aluminium sulfate) or polyaluminium chloride.

6. Paper Industry
  • Acts as a retention aid, filler, and sizing agent.

  • Enhances brightness, opacity, and printability of high-grade paper.

7. Cosmetics & Personal Care
  • Used in deodorants, toothpastes, and skin creams as a pH buffer, opacifying agent, and abrasive.

8. Glass Reinforced Plastics (GRP) & FRP Industry
  • Acts as a flame retardant filler in fiberglass laminates and resins.

9. Polishing & Abrasives
  • Ultra-fine grades used in metal polishing, optical lens polishing, and semiconductor wafer finishing.

10. Electronics & Battery Applications
  • Used in the manufacture of alumina substrates, electrolytic capacitors, and battery separators (after calcination to alumina).

�� Key Benefits:
  • Halogen-free flame retardant.

  • Low smoke emission.

  • Cost-effective white pigment/filler.

  • Safe for pharmaceutical and personal care applications.
