Aluminum Hydroxide FAQ: Specifications, Ordering and Support Questions

This FAQ brings together the questions that buyers, distributors, and procurement teams most commonly ask about this versatile industrial chemical — covering what it is, its published technical data, how it functions as a flame retardant, and the industries it serves.

What is aluminum hydroxide and what does it look like?

It is a white, amorphous powder that is insoluble in water. Its stable chemical structure ensures consistent performance in demanding industrial environments across pharmaceuticals, cosmetics, and manufacturing.

What are the published technical specifications for the HA-H grade?

The data below come from the published product information for the HA-H brand grade:

How does it function as a flame retardant?

When exposed to elevated temperatures, the material undergoes an endothermic decomposition that releases water vapor. This cools the surrounding substrate and dilutes combustible gases — a dual mechanism that inhibits flame spread and suppresses smoke. These properties make it a widely used ingredient in cables, building materials, textiles, and automotive components.

In what industrial sectors is it used?

The compound serves a broad range of sectors:

• Flame-retardant materials: Inhibits flame spread in cables, textiles, and building materials.
• Plastics, rubbers, and resins: Added as a functional filler to increase strength and hardness while reducing production costs.
• Ceramics: Acts as a filler and reinforcement agent, enhancing product strength and durability.
• Glass manufacturing: Functions as a flux to lower the melting point of raw materials, improving clarity and strength of finished glass.
• Aerospace, chemical, and electronics industries: Valued for thermal and chemical stability under high temperatures and in corrosive environments.

Can it be used as an antacid or in pharmaceutical applications?

Yes. The material is widely used in the pharmaceutical industry as an antacid to neutralize excess stomach acid and relieve heartburn and indigestion. Its biocompatible, non-toxic profile also supports use in pharmaceutical intermediates and acid/alkali-resistant materials.

What are its cosmetics applications?

In cosmetics, the compound is valued for its gentle exfoliating properties and is used as an ingredient in facial scrubs and other skincare products where mild abrasion is beneficial.

How does it improve plastics, rubber, and composite materials?

When added as a filler, it increases the structural strength and hardness of plastics, rubbers, and resins while reducing raw material costs. This combination of performance and cost efficiency makes it attractive for manufacturers of plastic products, rubber goods, and composites.
