As a new type of filled flame retardant, magnesium hydroxide releases bound water by thermal decomposition and absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material it fills in the flame, which inhibits polymer decomposition and The generated combustible gas acts to cool. Next, we will introduce the flame retardant mechanism of magnesium hydroxide flame retardant.
Magnesium hydroxide decomposes when heated to absorb heat from the surface of the combustion product to flame retardant; at the same time, it releases a large amount of water to dilute the oxygen on the surface of the fuel, and the activated magnesium oxide decomposed to adhere to the surface of the combustible material further prevents the combustion from proceeding. Magnesium hydroxide has no harmful substances in its flame retardant process, and its decomposed products can absorb a large amount of harmful gases and fumes generated by the combustion of polymers such as rubber and plastics while being flame retardant. Active magnesium oxide continuously absorbs incomplete combustion. The molten residue is an emerging environmentally friendly inorganic flame retardant that avoids smog and prevents droplets from burning quickly.
Magnesium hydroxide has high decomposition ability, high flame retardant efficiency, strong smoke suppression ability, low hardness, and low friction to equipment, which helps to extend equipment life. I hope that the relevant introduction of the above content can help everyone understand more about magnesium hydroxide flame retardant.
