Product Description
Product Description
Ultrafine magnesium hydroxide is kind of inorganic additive flame retardant,under thermal decomposition,release water and absorb latent heat to lower temperature of materials' surface,can inhibit polymer decomposition of combustible gas and cooling effect.At the same time, it generated magnesia refractory which can improve high synthetic material's ability to fight fire.It 's better than aluminum hydroxide in the decomposition temperature,
Using polymer range, from several aspects, such as flame retardant and smoke suppression ability hydroxide,for example:
1,Magnesium oxide which decomposed from magnesium hydroxide have better disacidify ability than aluminum hydroxide, can quickly neutralize acid and corrosion occurring in the process of plastic burning aerosols.
2,The thermal decomposition temperature of magnesium hydroxide was higher than aluminum hydroxide, so adding hydrogen and oxygen Of magnesium flame retardant plastic can withstand the higher processing temperature.
3,The decomposition ability of magnesium hydroxide is higher than aluminum hydroxide, also has a higher heat capacity, which help to improve the flame retardant efficiency.
4,magnesium hydroxide 's smoke suppression ability is better than aluminum hydroxide
5, The hardness of magnesium hydroxide particles is smaller than aluminum hydroxide and have less friction,it's better to prolong the life of production equipment.
