Heavy High Purity Magnesium Hydroxide Flame Retardant Magnesium Hydroxide For Fire Retardant Material
Application
In today's society, the application of flame retardant materials has penetrated into all areas of people's lives, in which magnesium hydroxide flame retardant has become a bright star in the field of flame retardant materials with its unique advantages.
Thermal decomposition and heat absorption
When heated, magnesium hydroxide undergoes a thermal decomposition reaction that absorbs a large amount of heat, thereby lowering the temperature of the material and slowing down the rate of combustion. This heat-absorbing effect helps to reduce the surface temperature of the material, inhibit the decomposition of polymers and cool the flammable gases produced.
Gas Flame Retardant
When magnesium hydroxide decomposes thermally, it releases a large amount of water, which dilutes the combustible gases and reduces the oxygen concentration, thereby reducing the rate of combustion. This mechanism helps to reduce flame propagation
Refractory Covering
Magnesium oxide (MgO) produced by the decomposition of magnesium hydroxide is a good refractory material that covers the surface of the polymer, blocking heat conduction and heat radiation and increasing the polymer's resistance to flame. This helps to insulate air and prevent combustion
Neutralizes acidic and corrosive gases
MgO quickly neutralizes acidic and corrosive gases produced by burning plastics, making it environmentally friendly.
Non-toxic and environmentally friendly
The decomposition products of magnesium hydroxide are water vapor and magnesium oxide, both of which are non-toxic and will not harm the human body. This makes it a better choice than phosphorus and halogenated flame retardants, especially in the context of the European Union, which has restricted the use of phosphorus and halogenated flame retardants.
