Magnesium hydroxide is an inorganic flame retardant filler for polymer matrix composites. Like aluminum hydroxide, magnesium hydroxide flame retardants act as flame retardants by chemical decomposition and heat absorption when heated, so they have the advantages of non-toxic, low smoke and stable chemical properties and no secondary pollution.
The addition of non-metallic compounds to polymer materials as fillers and flame retardant materials can not only reduce the production cost, but also reduce the combustion performance of polymer materials and kill two birds with one stone. as inorganic flame retardant filler, magnesium hydroxide flame retardant has the characteristics of non-toxic, non-smoking, non-halogen, non-corrosive and good thermal stability. Because of the safety and environmental protection characteristics of magnesium hydroxide, it is widely used in plastics, cables, rubber and other industries.
