Magnesium hydroxide flame retardant stands out

There are many kinds of flame retardant, magnesium hydroxide is undoubtedly the best flame retardant effect, because it will decompose when heated to release the bonded water to absorb a large amount of latent heat, reduce the surface temperature of the filled synthetic materials in the flame. More critical is that magnesium hydroxide not only can flame retardant, but also can suppress smoke, most of the time when fire occurs is due to the smoke is too large, resulting in people can not escape, magnesium hydroxide can be a good solution to this problem, adding magnesium hydroxide flame retardant can greatly reduce the smoke when burning, reducing the risk of death due to smoke asphyxiation.

Magnesium hydroxide flame retardant also has the advantage of environmental protection and non-toxic, this advantage makes its demand is very large, the application range is particularly wide, such as #rubber, #chemical, #building materials, #plastics, #electronics, #paints, #coatings and other industries will use magnesium hydroxide.

  We look at a few magnesium hydroxide and aluminum hydroxide comparison of several advantages.

1. magnesium hydroxide flame retardant cost-effective, nearly double the price of aluminum hydroxide than the filling volume is large.

2. magnesium hydroxide thermal decomposition temperature of 340 ℃, 100 ℃ higher than aluminum hydroxide, conducive to plastic processing temperature, speed up extrusion, improve the plasticization effect, shorten the molding time, the product surface glossy, will not produce surface defects, at the same time, to ensure a super peel strength.

3. magnesium hydroxide generated after burning dehydration is a high-strength, high heat-resistant material, can be used as a layer of protective wall, isolate the fire source and toxic and harmful gases, magnesium hydroxide and acid neutralization ability, can be faster to neutralize the acidic gas generated by the process of burning plastic.

4. The physical form of magnesium hydroxide is powder or granular, this form is conducive to uniform distribution, good compatibility with the substrate, the mechanical properties of the product is small.

It can be seen that magnesium hydroxide is a very ideal flame retardant, is used in a variety of industries, we believe that with the increasing demand for environmental pollution problems, the development trend of magnesium hydroxide flame retardant will also be better and better.
