We offer Aluminium Hydroxide, Al (OH) 3 which is 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 as one of the largest volume flame retardant 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, and ion exchanger, mordant, antacid, and filtering medium. Further, Aluminium Hydroxide can also be used in manufacturing of paper, ceramics, printing inks, detergents, for waterproofing fabrics and in dentrifrices and antiperspirants.
