Physical and chemical properties:

Superfine Aluminum hydroxide, a kind of white loose powder, has high whiteness and low bulk density. It is stable at room temperature and turned into alumina under being heated, decomposed and dehydrated. This product is different from other flame retardant material, because it does not produce toxic and corrosive gas. Heat absorption and water vapor release under heat make it a good one with flame retardant and self-extinguishing performance. Thus, to add this aluminum hydroxide in the advanced composite materials such as plastic, rubber, will make products have flame retardant and smoke abatement effect, and enhance its resistance to electricity leakage, arc and abrasion.

Applications:

It is widely used in flame retardant additive of flammable materials like all kinds of aluminum raw material, plastics and rubber. It can also be used in paper making, surface color, coating, toothpaste base material, catalyst carrier, purifying agent, fluoride salt, drying agent, different molecular sieve, pharmaceuticals industry, artificial agate, mosaic glass, quick setting agent of building material, etc.
