  Description & Application

   

   

  Magnesium Hydroxide appears in off white powder made from natural brucite ores with excellent performance on flame retardancy and smoke abatement. It’s non-halogenated with good heat stability, decomposition temperature at 330 degree, especially suitable for resin processing. It is a non-toxicity and low corrosion product. Magnesium hydroxide is an excellent flame retardant for use in rubber, chemicals, building materials, plastics (polypropylene, polyethylene, PVC, EPDM rubber) and electronic, unsaturated polyester and paint, coatings and other polymer materials ,especially for mining duct coated fabric, PVC the whole core conveyor belt, fire-retardant blankets, tarpaulins, PVC wire and cable materials, mining cable sheath, cable accessories flame, smoke and anti-static, can replace the aluminum hydroxide with excellent flame-retardant performance.

  dectiption

  High-purity magnesium hydroxide 99.9% English Name: Magnesium hydroxide Molecular Formula: Mg(OH)2 Molecular Weight: 58.32 Physicochemical Properties: White crystalline or powder; and its aqueous solution show alkaline reaction; 2.36g/cm3. It is soluble in diluted acid and ammonium salt solution and almost insoluble in water and alcohol. Its solubility 18in water is 0.0009g/100g. It is easy to absorb carbon dioxide in the air. When it is heated to above 200 in alkaline solution, it will become hexagonal crystal system crystalline. At 350, it shall decompose into magnesium oxide and water, and change into magnesium oxide by losing water above 500. Use: Magnesium Hydroxide is excellent flame retardant for plastics and rubber articles. In environmental protection field, it can replace caustic soda and lime as neutralizing agent for acid-containing wastewater. And it also can be used as additive for oil products with corrosion resistance and desulfurization functions. In addition, it can be used in electronic and medicine trade, refining of granulated sugar and also as thermal insulation material as well as for producing other magnesium salt. Processing Method: Brine-lime method, brine-ammonia method Target         Type Class  Name of items MHY1 MHY2 MHY3 MHY4 High- class First- rate High- class First- rate High- class First- rate High- class First- rate Content of magnesium hydroxide %       ≥ 99 97 96 96 Acid impurities%       ≤ 0.02 0.03 0.02 0.03 0.02 0.03 0.02 0.03 Moisture%≥           0.3 0.5 0.3 0.5 0.3 0.5 0.3 0.5 Content of chloride ≤ 0.15 0.25 0.15 0.25 0.15 0.25 0.15 0.25 Whiteness       ≥  92 90 92 90 92 90 92 90 Content of Fe      ≤ 0.03 0.03 0.03 0.03 Average size(μm)   0.4-1.2 0.4-1.2 0.4-1.2 0.4-1.2 Comparison(m2/g) 5-10 5-10 5-10 5-10 Accumulated(g/cm3)
