Aluminium Hydroxide Powder, also known as alumina trihydrate (ATH) or aluminum trihydroxide, has various uses and applications in different industries, including paint, construction, composites, and more.
Here are some common applications:
Flame Retardants in Paints and Coatings:
Aluminium hydroxide is often used as a flame retardant in paints and coatings. When exposed to high temperatures, it releases water vapor, which helps in cooling and inhibiting the spread of fire. This is particularly important for fire safety in buildings and industrial settings.
Construction Materials:
In the construction industry, aluminium hydroxide is used in various applications:
As a flame retardant in building materials such as fire-resistant panels, cables, and insulation.
In concrete formulations to enhance fire resistance and reduce smoke generation.
In coatings and sealants to improve fire resistance and thermal stability.
Composite Materials:
Aluminium hydroxide is commonly used as a filler or reinforcement in composite materials, including:
Polymer composites: It can be added to plastics and resins to improve their flame retardant properties and increase mechanical strength.
Fiberglass composites: It is used as a filler in fiberglass-reinforced composites to enhance fire resistance and reduce smoke emissions.
Pharmaceuticals and Antacids:
Aluminium hydroxide is used as an antacid to neutralize excess stomach acid in medications for gastrointestinal conditions. It helps relieve symptoms of heartburn and indigestion.
Water Treatment:
It is sometimes used in water treatment processes to adjust pH levels and remove impurities from drinking water and wastewater.
Cosmetics and Skincare Products:
Aluminium hydroxide can be found in cosmetics and skincare products, particularly in products like foundation and sunscreen, where it acts as a thickening agent and provides a matte finish.
Ceramics and Glass Manufacturing:
It can be used in ceramics and glass manufacturing as a source of alumina, which is an essential component in the production of ceramic glazes, glass, and refractory materials.
Paper Manufacturing:
Aluminium hydroxide is used as a filler and coating pigment in the paper industry to enhance paper quality, brightness, and opacity.
Flux in Metallurgy:
In metallurgy, aluminium hydroxide can be used as a flux in the production of non-ferrous metals like aluminum. It helps remove impurities from ores and enhances the melting process.
Plastics and Rubber Industry:
It is utilized as a flame retardant and filler in plastics and rubber products to improve fire resistance and mechanical properties.
Aluminium hydroxide’s versatility in various applications is largely due to its flame-retardant properties, low toxicity, and ability to act as a filler or reinforcement material. Its use is driven by the specific requirements and regulations within each industry.
