magnesium hydroxide flame retardant powerder magnesium hydroxide food grade

White crystal or powder. Soluble in dilute acid and ammonium salt solution, almost insoluble in water and alcohol. Easy to absorb carbon dioxide in humid environments. When heated above 200℃ in alkaline solution, it becomes hexagonal crystal system. At 230 ° C it decomposes into magnesium oxide and water. Above 500 ° C the loss of water converts to magnesium oxide. The aqueous solution is alkaline, pH 9.5 ~ 10.5.

Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In terms of environmental protection, as a flue gas desulfurizer, it can replace caustic soda and lime as a neutralizer of acid containing wastewater. It is also used as an oil additive to prevent corrosion and desulfurization. In addition, it can also be used in the electronics industry, medicine, sugar refining, as insulation materials and the manufacture of other magnesium salt products.
