Application

Aluminum hydroxide is the most widely used inorganic flame retardant additive.Aluminum hydroxide as a flame retardant can not only flame retardant, and can prevent smoke, do not produce droplets, do not produce toxic gas, therefore, has been widely used, the use is increasing year by year.Application scope: thermosetting plastics, thermoplastics, synthetic rubber, coating and building materials and other industries.At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride needed in electrolytic aluminum industry, aluminum hydroxide is also widely used in this industry.
