Magnesium hydroxide is an environmentally friendly inorganic green flame retardant and smoke suppressant with multiple functions of flame retardancy, smoke suppression, filling and heat absorption and cooling. It releases crystal water to dilute oxygen when heated and decomposed. It is non-toxic, halogen-free, non-corrosive and pollution-free with high thermal decomposition temperature, suitable for high-temperature processed rubber and plastic materials, widely used in various low-smoke and non-toxic flame retardant systems.
