Mg(OH) 2≥ 98% Flame Retardant High Purity Magnesium Hydroxide Mg(OH)2 For Fire Retardant Coating

Application

Magnesium hydroxide is a new type of filler flame retardant, through the thermal decomposition of the release of bound water, absorbing a large amount of latent heat to reduce the surface temperature of the synthetic material it fills in the flame, with the inhibition of the decomposition of polymers and the role of the resulting combustible gases for cooling. The magnesium oxide generated by decomposition is a good refractory material, which can also help to improve the fire-resistant performance of synthetic materials, and at the same time, the water vapor it releases can also be used as a smoke suppressant.

Higher decomposition energy and high heat capacity

The decomposition temperature of magnesium hydroxide is 340~490℃, which can make the filled material bear higher processing temperature, which is helpful to speed up the extrusion speed and shorten the molding time. Moreover, the decomposition energy of magnesium hydroxide is bigger and the heat capacity is high, which can absorb more heat and have better flame retardant effect.

Low wear

The small particle size of magnesium hydroxide is less abrasive to the material processing equipment, which is conducive to prolonging the service life of the equipment.

Abundant and readily available raw materials

Raw materials are abundant and easy to obtain, seawater resources contain a large number of magnesium salts, as well as magnesium ore such as magnesite, dolomite and magnesite.
