Flame Retardants (ATH & MDH)

Aluminium hydroxide and Magnesium hydroxide allow the production of flame retardant compounds heavy metal and halogen free, with a very low smoke emission and a very interesting cost performance ratio. Due to his peculiar characteristics, ATH and MDH suitable to be used with a wide range of polymer, thanks to his high thermal stability.

Based on endothermic decomposition into Al oxide or Mg oxide and water 

  • Cooling of polymer 
  • Dilution of flammable gases 
ATH or Aluminium hydroxide or Aluminium TriHydrate 
  • 2 Al(OH)3 Al2O3 + 3 H2O needs 1051 J/g Al(OH)3 
  • Processing up to about 200°C
MDH or Magnesium hydroxide or Magnesium DiHydrate 
  • Mg(OH)2  MgO + H2O needs 1316 J/g Mg(OH)2 
  • Processing up to about 340°C


  • Highly effective / Achieve high level of fire safety
  • Economical to use
  • Environmentally acceptable & recyclable
  • Maintain resin properties
