  1.General Description
  Molecular formula: Mg(OH)₂
  CAS No.: 1309-42-8

  2.Applications
  our company along with Institute Of Chemistry Chinese Academy Of Sciences do the research and development of efficient halogen-free flame retardant magnesium hydroxide,Our products have multiple functions such as drip-proof, suppressing smoke ,material of filling.Magnesium hydroxide will decomposition when heated (340-490 degrees centigrade) ,at the same time release a lots of moisture to dilution the oxygen concentration on the surface of the comburent, decomposition by-product attached to the comburent surface and further to stop the burning fuel.In the whole process of flame retardant magnesium hydroxide didn't produce any harmful substances, and its decomposition by-product also absorbed harful gas and smoke from the burning of rubber, plastic and other polymer material , also drop proof function
  Magnesium hydroxide is a kind of good thermal stability, no pollution, environmentally friendly inorganic flame retardants.
