Flame Retardants (ATH & MDH)
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
- 2 Al(OH)3
Al2O3 + 3 H2O needs 1051 J/g Al(OH)3 - Processing up to about 200°C
- Mg(OH)2 MgO + H2O needs 1316 J/g Mg(OH)2
- Processing up to about 340°C
Why ATH OR MDH?
- Highly effective / Achieve high level of fire safety
- Economical to use
- Environmentally acceptable & recyclable
- Maintain resin properties
