Aluminium Hydroxide Properties

Aluminium Hydroxide

Description

 

Aluminium hydroxide sometimes erroneously called hydrate of alumina, is found in nature as the mineral gibbsite and its three, much more rare forms, polymorphs: bayerite, doyleite and nordstrandite. The major uses of aluminium hydroxide is as a feedstock for the manufacture of other aluminium compounds. Aluminium hydroxide also finds use as a fire retardant filler for polymer applications in a similar way to magnesium hydroxide and hydromagnesite. In addition to behaving as a fire retardant, it is very effective as a smoke suppressant in a wide range of polymers, most especially in polyesters, acrylics, ethylene vinyl acetate, epoxies, PVC, rubber.
