We offer Percipatated Aluminium Hydroxide, Al(OH)3, a non-abrasive powder with a Mohs’ hardness index of 2.5 – 3.5 and a specific gravity of 2.42. Aluminium Hydroxide is considered one of the largest volume flame retardants, as it can be heated to 200°C and hydrated alumina, can be decomposed into 66% alumina and 34% water. Aluminium hydroxide is also used as an adsorbent, emulsifier, ion exchanger, mordant, antacid, and filtering medium. Further, Aluminium Hydroxide can also be used in the manufacturing of paper, ceramics, printing inks, detergents, waterproofing fabrics and dentifrices and antiperspirants.


Aluminium Hydroxide is also known as Hydrated Alumina, Aluminium Trihydrate, Trihydrated Alumina, Aluminium (III) Hydroxide or Trihydroxy Aluminium.
