Magnesium Hydroxide Fire Retardant Additives (MDH)
Flame retardant. 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.
