Product Description

White Powder Aluminium Hydroxide Hydrate 21645-51-2 of AL(OH)3 65%


Aluminum hydroxide, chemical formula Al (OH) 3, is aluminum hydroxide. Aluminum hydroxide can react with acids to form salts and water and alkali reaction of salt and water, it is a kind of amphoteric hydroxide. Chemical formula Al (OH) 3, aluminum hydroxide. As a result of a certain degree of acidity, it can also be referred to as aluminum acid (H3AlO3). But the actual reaction with alkali generated is four hydroxy and aluminate ([Al (OH) 4]-). Therefore, it is usually regarded as a hydrated aluminum acid (HAlO2 / H2O), according to the use of industrial grade and pharmaceutical grade two.

The inorganic flame retardant additives of aluminum hydroxide is the largest amount and the most widely used. Aluminum hydroxide as a flame retardants can not only, but also can prevent smoke, don't drop things, does not produce toxic gases, therefore, obtains the widespread application, use also increased year by year. Usage: thermosetting plastics, thermoplastics, synthetic rubber, paint and building materials and other industries. At the same time, the basic raw material of aluminum fluoride aluminum hydroxide is necessary for electrolytic aluminum industry, but also get widely used in the industry of aluminum hydroxide.
