Product introduction:

Aluminum hydroxide, also known as hydrated alumina, is a halogen-free environment-friendly

 flame retardant. It can not only flame retardant, but also smoke suppression, no dripping 

and toxic gases, and its price is cheaper than that of halogen and phosphorus. It is the most

 widely used inorganic flame retardant. The company produced aluminum hydroxide flame 

retardant with ultra-fine, high purity, whiteness, uniform particle size distribution characteristics;

 the advanced surface treatment technology, polymer with good compatibility, in adding a large 

number of cases can be greatly reduced to the influence of the physical and mechanical properties of materials.



Name: aluminum hydroxide (Aluminium hydroxide)
CAS NO:21645-51-2

Flame retardancy mechanism

When the flame retardant is heated to a certain extent to absorb heat and vaporization

 concentration dehydration to produce H2O so as to reduce the fuel temperature and 

dilute combustible vapors and combustion gas, while the formation of oxide isolation layer 

on the surface of combustible materials, so as to achieve the purpose of combustible flame retardant.
