Why can be used as common magnesium hydroxide flame retardant

Magnesium hydroxide is a new kind of flame retardant, has been in the field of chemical industry of the flame retardant has replaced the traditional caustic soda and lime and aluminum hydroxide and aluminum oxide, and other flame retardants. In the commonly used flame retardant magnesium hydroxide are widely used. Why, then, can be used as a common flame retardant type magnesium hydroxide, added to the various kinds of polymer materials?

This is because its decomposition in the process of heat release of hydration, to absorb a large number of latent heat, and reduce the surface temperature of the flame of synthetic material filling. In addition, it also can inhibit the smoke. When the fire smoke produced heat conduction, people can't fled the scene, magnesium hydroxide is a good way to solve this problem, reduce the risk of the smoke choking. In addition to the flame retardant and smoke suppression, magnesium hydroxide also because of its environmental protection, non-toxic and widely favored by the people. Used in rubber, chemical industry, building materials, plastic, electronics, paint, paint and other industries.
1. Cost-effective, magnesium hydroxide flame retardant is added to the polymer which can realize high filling volume.
2. Magnesium hydroxide thermal decomposition temperature of 340 ℃, to improve plastic processing temperature, extrusion speed, improve plasticizing effect, shorten the molding time, products with high surface gloss and no surface defects, at the same time guarantee the super peel strength.
3. After burning magnesium hydroxide dehydrated magnesium oxide is a kind of high strength, high heat-resistant material, can be used as isolation wall fire and poisonous and harmful gas protection. Magnesium hydroxide and has strong ability of neutralizing acid, can quickly neutralize plastic combustion process of acid gases.
4. The physical form of magnesium hydroxide as granular, is beneficial to uniform distribution, it has good compatibility with base material, the effects on the mechanical properties of the product is smaller.
