Ultrafine precipitated aluminum hydroxide is regular crystal structure products made by additional process. It has the benefits of high-purity, ultrafine-precipitated, regular crystal shape, low surface activity and small specific surface area, can be widely used in various of processing technology.

Aluminum hydroxide working principle is absorbing heat and decomposing into alumina and water, without generating toxic gas and corrosive substance, the decomposition process absorbs lots of heat during the polymer’s combustion, to prevent polymer rapid decomposition and delaying the formation of flammable by-products. The water vapor produced displaces oxygen to play a similar role of inert gas. A protective layer formed by alumina and carbon products on the surface of the polymer to suppress combustion and lower the smoke density.

The flame retardancy of Aluminum hydroxide mostly rely on Aluminum hydroxide dosage in the polymer compound, processing temperature is only slightly more than 200 ℃.

With an annual output of 100000 tons of fine precipitation of aluminum hydroxide industrial park is on construction, the first phase of an annual output of 20000 tons of projects have been completed and put into operation
