Activate magnesium
hydroxide
Activate magnesium hydroxide [Mg(OH)2]
is a new, intoxicate, multifunction flame and smoke retarder.
The magnesium hydroxide can delaying the ignition time of the material
and catalyze the oxide smoke, and the volumn of generated smoke
as well as the escaping speed of the smoke.
The magnesium hydroxide are produced by using high quality brucite,
adopt advanced process and superfine powder equipments, and enveloped
by imported silane coupling agent, which easily disperse in highpolymer,
which can stand high-tem of up to 330 .
The product are widely used in PE, PP, PVC, ABS, PS, HIPS, PA, PBT,
unsaturated polyester, epoxy resin, rubber, paints as the flame
retarding agent, it also find its application in chemicals and environmental
protection arena.
