Flame retardant Magnesium hydroxide series Refractory material

Product Description Magnesium Hydroxide - Mg(OH)2 is a novel flame retardant filler which absorbs large quantities of latent heat through the bound water released in the decomposition once being heated, to reduce the surface tmeperature of the composite materials in the flame, meanwhile has the effect of inhibiting the decomposition of the polymer and cooling the combustible gas. The magnesium oxide generated in the decomposition is also a good type of refractory material. Magnesium Hydroxide is recognized as a kind of tape of excellent flame retardant with three functions of Halogen free, Smoke suppression and Filling function in the Rubber & Plastic industry.    Magnesium Hydroxide Flame Retardant is widely used in rubber, chemicals, building materials, electronics, plastic, unsaturated polyester, paint, coatings and other polymer materials. Product Features

Halogen free

Smoke suppression

Filling function

  Magnesium hydroxide is decomposed in the temperature range of 340℃ - 490℃, the absorptive capacity of which is 783.6 J/g. The initial decomposition temperature of magnesium hydroxide is much higher than aluminum hydroxide, with strong thermal stability, excellent flame retarding & smoke suppression effect, especially applicable to the Polyolefin materials with high process temperature. Company Profile We, Xinyang Minerals Group, located in the beautiful coastal city of Dalian, is the largest manufacturer & supplier of magnesium mineral products in China. The group actively expands domestic and foreign markets, currently has established long – term – stable supply & demand relationships with more than 50 countries and regions, such as Europe, America, Southeast Asia, Russia, Japan, Korea, India and so on. We not only has dozens of mines, including magnesium hydroxide mine, magnesite mine, marble mine, potassium feldspar mine, dolomite mine and chlorite mine, but also owns a magnesium hydroxide mine – NuanheMine, of which the Proved Reserves is the largest in China. Total reserves of all levels of magnesium mines exceed one hundred million tons, with thick orebody, high grade and stable quality features, continues providing high – quality, safe and stable products for the development of  industrial in China. Mechanism Magnesium hydroxide, a novel flame retardant filler, absorbs large quantities of latent heat through the bound water released in decomposition process when being heated. The proceed mentioned above, which can reduce the surface temperature of the composite materials in the flame, has the effect of inhibiting the decomposition of the polymer and cooling the combustible gas. Magnesium oxide generated in the decomposition, a high grade refractory material, can not only improve the fire resistance of the synthetic materials, but also absorb a large quantities of noxious gas and smoke. Magnesium hydroxide is considered as an excellent flame retardant with three functions of flame retarding, smoke suppression and filling in the rubber & plastic industrial. It also has been considered as one of the most effective and harmless flame retarding product all over the world. Magnesium hydroxide is widely used in flame retarding, water treatment, flue gas desulfurization, magnesium oxide preparation, fluxing and so on. Specification Average Particle Diameter
