Magnesium hydroxide has a a good application prospect, is a kind of inorganic flame retardant filler of HPMC. Magnesium hydroxide plays the role of inflaming retarding by heat absorption and release water when heated. The same as aluminum hydroxide, it has the advantages of non-toxic, low smoke and generated magnesium oxide with stable chemical properties, and does not produce secondary pollution.
Magnesium hydroxide can be used in drug, additives or other industries, also be used for flame retardant plastic products. As a new kind of flame retardant material, magnesium hydroxide plays a great role. Magnesium hydroxide filler material decomposition and release when heated, mixed with water it absorb a large number of heat, synthetic material filling in the flame, can inhibit the decomposition of the polymer and the cooling of the combustible gas production.
Magnesium hydroxide is also a kind of refractory, can help to improve the fire resistance performance of composite materials, meanwhile water vapor it produced can be used as smoke suppressor. It is widely used in rubber, chemical industry, building materials, plastics and electronics, unsaturated polyester resin, paint and other polymer materials.
