what is superfine magnesium hydroxide

Childe formula: Mg (OH) 2


Molecular weight: 58.32 product introduction: magnesium hydroxide is an excellent flame retardant with triple functions of flame retardant, smoke suppression and filling in the rubber and plastic industry. White powder, with non-toxic, tasteless, good stability, non-volatile, high decomposition temperature and no corrosion to equipment, is the first choice for organic polymer to realize halogen-free flame retardant. Product characteristics: magnesium hydroxide flame retardant releases feed water during thermal decomposition and absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material filled in it in the flame. It can inhibit the decomposition of polymer and cool the generated combustible gas. The decomposed magnesia is a good refractory and can also help improve the fire resistance of the material. At the same time, the water vapor released by it can also be used as a smoke suppressant. The fine magnesium hydroxide and composite active superfine magnesium hydroxide flame retardant sold by the company have good product performance. The initial decomposition temperature is 340 ℃ and the complete decomposition reaches 490 ℃. They are suitable for high-temperature mixing processing. They have good dispersion and fluidity in the basic resin, maintain the mechanical strength of the material and improve the compatibility with polyester. The superfine magnesium hydride sold by our company has been surface treated, which is especially suitable for high filling environmental protection low smoke halogen cable material (Note: for customers who buy magnesium hydride supplied by our company, we can provide low smoke halogen-free cable material formula or assist in its successful development). Scope of application: it can be widely used in PP, PE, PVC, EVA, PS, hips, ABS and other plastics Rubber is used as flame retardant or flame retardant filler. In addition, it can be used as neutralizer in dye, grease and other industries, and can meet the requirements of halogen-free flame retardant of wires and cables. Moreover, it is applicable to non-toxic or low smoke, low toxic and flame retardant industries, such as subway, power station, aircraft, ships, elevators and indoor decoration materials.
