One of the main purpose of magnesium oxide is used as flame retardants. As the traditional flame retardant materials, it is widely made of flame retardant mixture, containing halogen polymers or containing halogen flame retardants. But once there is a fire, as a result of pyrolysis and combustion, it will produce a lot of smoke and toxic and corrosive gas to prevent fire fighting and personnel evacuation, instruments and equipment corrosion. Especially it has been found that, there are more than 80% death accidents in fire is caused by material of smoke and toxic gases, except the flame retardant efficiency, low smoke and low toxic are also the indispensable requirements for flame retardant. China flame retardant industry development is not balanced, proportion of chlorine is flame retardant, most in the flame retardants, including chlorinated paraffin monopoly. But when the chlorine flame retardant role, releasing toxic gas, there is a big distance between the non-toxic with modern life pursues high efficiency. So in order to adapt to the flame retardant low smoke, low toxicity and the development trend of pollution-free, it is imperative to the development, production and application of magnesium hydroxide flame retardant.
From the current master, magnesium oxide as a flame retardant has very broad prospects for development, as the replacement of traditional flame retardant effect is more and more attention, the market prospect of the magnesium oxide will be brighter.
