Aluminum Hydroxide Flame Retardant
Molecular Formula: Al(OH)3
H.S. CODE: 2818 3000
CAS No.:21645-51-2
EINECS No.:244-492-7
Aluminum hydroxide serves as an effective flame-retardant filler, primarily comprising Al (OH)3.
This white micro powder exhibits no secondary pollution, rendering it an environmentally benign inorganic flame retardant.
Aluminum hydroxide confers flame retardancy, smoke suppression, filling properties, antistatic characteristics, and more to products. Notably, it offers advantages such as cost-effectiveness, high performance, stability, non-volatility, non-corrosiveness to equipment, and a high decomposition temperature.
