The unique advantages of magnesium hydroxide as a flame retardant

Hebei Messi Biology Co., Ltd. said that there are many materials spontaneous combustion point is actually very low, then in order to stop them from spontaneous combustion, engineers will add some flame retardant, magnesium hydroxide is a very good flame retardant material, then why it can be used as a flame retardant? The following is to explain the mystery.

Magnesium hydroxide is a new type of filler-type flame retardant, through the heat differentiation when the release of combined water, absorbing a large amount of latent heat to reduce the composition of the material it fills in the flame in the appearance of the flame temperature, with the polymer to press down on the differentiation and the combustible gases occurring in the role of cooling. Magnesium hydroxide as a flame retardant has the following five unique advantages:

Flame Retardant Magnesium Hydroxide

1, magnesium hydroxide incineration and dehydration after the generation of magnesium oxide is a high-strength, high-heat-resistant materials, can be used as a layer of protective wall, blocking the fire source and toxic and harmful gases, magnesium hydroxide and acid neutralization ability is strong, and can be faster and plastic incineration process occurs in the acidic gases SO2, NOx, CO2, etc.;.

2, uniform particle size distribution, good compatibility with the substrate, the mechanical properties of the finished product has little effect.

3、Magnesium hydroxide has high differentiation capacity, high flame retardant efficiency, strong smoke suppression capacity, low hardness, small friction on the equipment, which helps to extend the life of the equipment.

4, magnesium hydroxide thermal differentiation temperature of 340 ℃, 100 ℃ higher than aluminum hydroxide, is conducive to the progress of the plastic processing temperature, speed up the extrusion speed, improve the role of plasticization, shorten the time of molding, the finished product has a high degree of glossy appearance, will not occur appearance defects, to ensure that has a superb peeling strength.

5, cost-effective, magnesium hydroxide relative to the price of aluminum hydroxide is much lower, filling volume, can significantly reduce costs.
