Decriptions
Magnesium hydroxide(Brucite Powder) is a physical flame retardant
with three functions of flame retardant, smoke limited and filling
in rubber and plastics. It has the characteristics of non-toxic,
odorless, good stability, non-volatile, well dispersion,
non-corrosive, etc. And it is the preferred option of filler
material for polymer material with effective flame retardant.
Magnesium hydroxide(Brucite Powder) flame retardant releases water when it is thermally decomposed, absorbs a large amount of latent heat to reduce the surface temperature of the synthetic polymer material with filling brucite powder , and has the functions of inhibiting polymer decomposition,meanwhile cooling the generated flammable gas. The decomposed magnesium oxide is also a good flame retardant material, which can help improve the fire resistance of synthetic polymer materials, and the water vapor it releases can also be used as a smoke limited.
