Product Description

Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH)3, which is the hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water, and can react with strong base to form salt and water, so it is an amphoteric hydroxide. Because of its certain acidity, it can also be called aluminate (H3AlO3). However, what is actually formed when it reacts with a base is tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as metaaluminate monohydrate (HAlO2·H2O), which is divided into two types: industrial grade and pharmaceutical grade.
The main purpose
Aluminum hydroxide is the largest and most widely used inorganic flame retardant additive. As a flame retardant, aluminum hydroxide can not only be flame retardant, but also prevent smoke, no dripping, and no toxic gas. Therefore, it has been widely used, and the amount of use is increasing year by year. Scope of application: Thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for the electrolytic aluminum industry, and aluminum hydroxide is also widely used in this industry.
