General description
Magnesium hydroxide is a low corrosive inorganic compound that is widely used as an acid- and halogen-free flame retardant and smoke suppressant in various polymeric matrices in the plastics industry. It is a magnesium oxide intermediate that can be used in refractory, water and wastewater treatment, fuel gas desulfurization, pulp and paper industry, and as a fertilizer additive.
Application
Magnesium hydroxide can be used as:
- A filler to prepare kenaf fiber-reinforced polymer composites.
- A pH-adjusting agent in the production of succinic acid.
