Product Description
Technical Date Sheet:
Molecular Formula: Al(OH)3
H.S. CODE: 2818 3000
CAS No.:21645-51-2
EINECS No.:244-492-7
Aluminum hydroxide, a white powder, serves as both a flame retardant and filler. In resin solid surface applications, it exhibits characteristics such as white crystalline structure, non-toxicity, tastelessness, excellent flowability, low oil absorption, minimal iron content, well-defined particle morphology, uniform particle size distribution, low impurity levels, robust stability, high whiteness, and superior dispersibility.
