Magnesium Hydroxide Fire Retardant Additives (MDH)

Huber’s magnesium hydroxide (MDH) products are flame retardants and smoke suppressants utilized in applications where processing temperatures are above 200°C.

While having the same fire retardant mechanism as ATH, there is one key difference: MDH undergoes endothermic decomposition when water is released at 330°C or 626°F.  (ATH decomposes at 220°C.)  That means it is thermally stable at temperatures up to 110°C higher than ATH.

Formulators can also blend MDH with ATH to achieve improved flame retardancy in a variety of polymer systems.  Click here to learn more about blending.
