MAGNESIUM HYDRATE (Mg(OH)2)

Properties:Nowadays magnesium hydrate is generally considered as an excellent fire retardant in the field of rubber-plastic industry for its triple function inflaming retarding, smoke restraining and packing. Its molecular formula is Mg (OH) 2 and the molecular weight is 58.32 . It is a kind of nontoxic, and high decomposition temperature. And it doesn’t corrode equipments. So it is the first selected material to be used as organic high-polymer for producing non-halogen ting inflaming retarding. Magnesium hydrate fire retardants reduce the surface temperature of the flame, in which the synthetic materials are packed, by releasing hydrate water and absorbing a large amount of latent heat. These functions are restraining polymers from composition is also a good fire-retardant material and can help to improve the refractory property of the synthetic materials, while the emitted vapor can be used as a kind of restraining smoke agent.
