Aluminum Hydroxide
CAS NO.:21645-51-2
Molecular Formula：Al(OH)3
Aluminium hydroxide micro powder is currently recognized as an inorganic additive with triple functions of flame retardant, smoke suppression and filling in plastic industry. Non-toxic, tasteless, good stability, non-volatile, high decomposition temperature, there is no secondary pollution during combustion, not only good dispersion in the polymer, but also easy to produce synergistic effect of flame retardant with other additives. It can be widely used in unsaturated polyester, epoxy resin, thermoplastic, synthetic rubber, composite materials and other products
It is the best choice for organic polymer to achieve halogen free flame retardant.
