1. What Is Aluminium Hydroxide?

Aluminium hydroxide (ATH) is a white powder created from high-purity sodium aluminate solution. The material has high brightness, stable chemical properties, and low oil absorption. Many industries use it because it is safe, non-toxic, and easy to process. When people ask what is aluminium hydroxide used for, the answer depends on the purity, fineness, and modification of the product.

2. What Is Aluminium Hydroxide Used For?

Aluminium hydroxide has many uses. The main industries include:

  • Flame retardants for plastics and rubber
  • Fillers for PVC, EVA, and artificial marble
  • Catalyst carriers and adsorbents
  • Ceramics and high-temperature materials
  • Pharmaceutical antacids
  • Water treatment chemicals

Each application uses a different grade. That is why choosing the right Manufacturer or Factory is important.

3. Aluminium Hydroxide in Flame Retardants

One of the most common answers to what is aluminium hydroxide used for is flame retardant production. ATH releases water when heated. This cools the material and reduces smoke. Because it is halogen-free, it is safer than traditional flame-retardant additives.

Main industries include:

  • Wires and cables
  • PVC sheets
  • EVA foam
  • Silicone rubber
  • Insulation boards

For high-end flame retardants, customers often use:

4. Aluminium Hydroxide as Industrial Fillers

Aluminium hydroxide is a popular filler in plastics, coatings, and engineered stone. It improves whiteness, strength, and aging resistance. It also reduces cost while keeping material performance stable.

Industries that use ATH fillers:

  • Artificial marble and solid surface
  • PVC window profiles
  • Cable compounds
  • Rubber sheets
  • PVC flooring

8. Water Treatment Uses

What is aluminium hydroxide used for in water treatment? It is used to produce coagulants like PAC and other aluminium-based flocculants. These help remove impurities in drinking water, wastewater, and industrial water.

9. Types and Grades of Aluminium Hydroxide

The answer to what is aluminium hydroxide used for depends on grade selection. Main grades include:

  • Standard aluminium hydroxide
  • High whiteness grade
  • Low-Na grade
  • Surface-modified grade
  • Ultra-fine grade

Different industries use different grades to achieve the best effect.
