CAS No.:21645-51-2
EINECS No.:244-492-7
Aluminum Hydroxide is a white powder which can be used as flame retardant and filler.
While it is used for resin Solid Surface,It has characteristic of white crystalline powder, non-toxic, tasteless, good mobility, low oil absorption, low iron content, particle morphology, particle size distribution, low impurity content, good stability, high whiteness, uniform particle size and good dispersibility.
While it is used for composite materials,it has characteristic of micro powder,high white powder without secondary pollution,smoke elimination, filling, antistatic.The initial decomposition temperature of aluminum hydroxide is about 205 ºC. Aluminum hydroxide flame retardant can release a large amount of water vapor when heated. A large amount
of water vapor can store heat and dilute the concentration of polymer combustible gas. It can also
form a non combustible barrier between the combustion source and the matrix material to achieve
the purpose of flame retardance. At the same time, it is also a smoke suppressant, because the gas
it releases is water vapor, which has no corrosion to metals.
ATH Filler for Solid Surface can improve the anti-leakage, arc resistance, wear resistance and anti-aging performance of the products.
Ground Aluminum Hydroxide Ath Powder is mainly used in BMC and SMC production.
According to the different sizes of Aluminum Hydroxide Powder,it is also can be used in toothpaste friction agent, low-voltage insulation devices, plastic, rubber, glass fiber reinforced plastic,adhesives, grille, carpet and other industries which required flame retardant.
