2.Applications
Aluminum hydroxide is the most consumable and applicable inorganic additive flame retardant that does not only resist firing, but also prevents from smoke, dropping or toxic gas. So, it is widely used with gradual increase of the usage, at the sectors of hot solidifying and moulding plastic, synthetic rubber, coating and construction materials.also used as filler for artificial marble and PVC Wallpaper.

Aluminum hydroxide is also used for water treatment as low material for Aluminium sulfate, PAC and other salts.

Aluminum hydroxide is widely used in medical industry.
