High Purity Magnesium Hydroxide Flame Retardant Mg(OH)2 For Fire Retardant Material

Application

Magnesium hydroxide is a new type of filler-type 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.

Improved plasticisation and superior peel strength

The thermal decomposition temperature of magnesium hydroxide reaches 340℃, 100℃ higher than aluminium hydroxide, which is conducive to the increase of plastic processing temperature, speed up the extrusion speed, improve the plasticising effect, shorten the moulding time, and the surface gloss of the products is high, which will not produce surface defects, and at the same time, it guarantees superb peeling strength.

Strong neutralisation capacity

Magnesium hydroxide combustion and dehydration of magnesium oxide is a high-strength, high heat-resistant materials, can be used as a layer of protective wall, isolation of fire and toxic and harmful gases, magnesium hydroxide and acid neutralisation ability, can be faster neutralisation of plastic combustion process of acidic gases SO2, NOx, CO2 and so on;

Helps extend equipment life

High decomposition capacity of magnesium hydroxide, high flame retardant efficiency, strong smoke suppression capacity, low hardness, low friction on equipment, helping to extend the life of the equipment.

Inexpensive

Low price, is magnesium hydroxide is half the price of aluminium hydroxide, filling volume, can greatly reduce the cost of the product.
