Alumina Hydrate
Filler for flame retardant
Description
Hydrated Alumina of Alcoa Chemicals finds wide applications.
Features
Hydrated alumina, also known as alumina trihydrate (Al(OH)3), is white crystalline powder. On heating to 200
, hydrated alumina decomposes into 66% alumina and 34% water. Since it decomposes endothermically, it is used as flame retardant filler in plastics.

Hydrated alumina is a non-smoking, low toxicity halogen free flame retardant. When a properly loaded hydrated alumina/plastic compound is exposed to fire the hydrate begins to decompose endothermically into water and anhydrous alumina. The water acts as a heat sink, cooling the plastic and significantly slowing its degradation into combustible fuel.
Hydrated alumina increases arc resistance and lowers arc tracking rate.
White hydrated alumina is separated from a sodium aluminate solution containing few organic matters.
