Specifications
Introduction
Ultrafine precipitated FaRetarTM Al(OH)3 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.FaRetarTM Al(OH)3 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.

Application
FaRetarTM Al(OH)3 is the most consumable and applicable inorganic additive flame retardant. It not only resists firing, but also prevents from smoke, dropping or toxic gas. So, it is widely used in the sectors of hot solidifying and moulding plastic, synthetic rubber, coating and construction materials with gradual increase of the usage, at
