1. Product description
Using the bischofite as the raw material, the patented technology of producing high-purity magnesium hydroxide by the brine-ammonia-lime combined method is an important new inorganic chemical raw material for the development and production of high-purity magnesium hydroxide. The powder is the first choice for the preparation of various environmentally friendly inorganic magnesium hydroxide flame retardants. It has the triple functions of flame retardancy, smoke suppression and filling. When heated, it releases bound water and absorbs a large amount of latent heat to reduce it. The surface temperature of the filled synthetic material in the flame can inhibit polymer decomposition and cool the generated combustible gas. It can be widely used in engineering plastics, epoxy resins, rubber, wire and cable fillers, and mining cables. The flame retardant of sheath and cable accessories can replace aluminum hydroxide and has excellent flame retardant effect.
