Technical profile of Aluminium Trihydroxide, a high-purity raw chemical material supplied by Triveni Chemicals for industrial manufacturing and laboratory synthesis.

Technical Specifications:

CAS Number: 21645-51-2

Synonyms: Aluminum Hydroxide

Chemical Formula: AlH3O3

Industrial Uses & Applications:

Aluminium Trihydroxide Is A White, Inorganic Compound Widely Used As A Flame Retardant And Functional Filler In Industrial Applications. It Is Valued For Its Ability To Release Water When Heated, Thereby Reducing Flame Spread And Smoke Generation. Aluminium Trihydroxide Is Commonly Used In Plastics, Rubber, Cables, Coatings, Adhesives, And Construction Materials.

Versatile Flame Retardant and Filler

Aluminium Trihydroxide acts as a highly effective, non-toxic flame retardant and smoke suppressant. When exposed to high temperatures, it releases water molecules, inhibiting combustion in plastics, rubbers, and textiles. Its natural compatibility and safety make it essential in polymer formulations, enhancing fire safety without harmful effects.

Industrial Applications and Benefits

ATH serves not only in flame retardancy but also as a mineral filler, raw material for aluminium chemicals, and a polishing agent. Its fine particle size boosts physical properties and processability in end products, while its non-toxic, odorless nature ensures safety during handling and use. It is widely preferred for industrial-grade applications.

FAQ's of Aluminium Trihydroxide (21645-51-2):

Q: How is Aluminium Trihydroxide typically used in industrial applications?

A: Aluminium Trihydroxide is commonly used as a flame retardant and smoke suppressant in plastics, rubbers, and textiles. It also functions as a mineral filler, polishing agent, and as a precursor for aluminium fluoride and high-purity aluminium oxide in the chemical industry.

Q: What benefits does Aluminium Trihydroxide offer compared to other flame retardants?

A: Unlike many other flame retardants, Aluminium Trihydroxide is non-toxic, releases no harmful by-products, and effectively suppresses smoke by decomposing above 300C to release water vapor instead of toxic gases. This provides enhanced fire safety in end-use applications.

Q: When does Aluminium Trihydroxide decompose, and what happens during decomposition?

A: Aluminium Trihydroxide decomposes at temperatures above 300C. The decomposition process releases water vapor and results in the formation of alumina (Al2O3), which helps suppress flames and inhibit the spread of fire.

Q: Where can Aluminium Trihydroxide be sourced and in what packaging?

A: Aluminium Trihydroxide is available from chemical manufacturers and suppliers in India and globally. It is usually packed in 25 kg or 50 kg HDPE or polypropylene bags for safe transport and storage.

Q: What is the shelf life and storage recommendation for Aluminium Trihydroxide?

A: Aluminium Trihydroxide has a shelf life of 12 months when stored in a cool, dry place, away from moisture and incompatible materials. Proper storage ensures the product retains its properties and effectiveness.

Q: Is Aluminium Trihydroxide toxic or hazardous for users?

A: No, Aluminium Trihydroxide is non-toxic and non-poisonous. It is safe to handle in accordance with standard industrial practices, though proper protective equipment is recommended during processing to prevent inhalation of fine dust.
