Magnesium Hydroxide


Magnesium Hydroxide is a white powder with a specific gravity of 2.36. , very slightly soluble in water; decomposing at 350°C. Magnesium Hydroxide is an inert filler, flame retardant and smoke suppressant for plastics, synthetic rubber, reinforced polyesters, phenolics and urethane foam. Magnesium hydroxide releases its 31% water when heated to above 325°C, Which cools the product below flashpoint to reduce fire occurrence. Medicinally it, in the form of a mixture (milk of magnesia), is also used as an antacid and as an osmotic laxative.
