Introduction

I. Product Introduction

China has abundant halogen resources, and this series of productsis prepared using halite MgCI2 + 2NH3 H2O  Mg(OH)2 + 2NH4CI. It has highpurity, good whiteness, and controllable particle size.

The high-purity ultrafine magnesium hydroxide powder with average particle size of1.5um, 3um, 5um and other different specifications is obtained by fine grinding and gradingprocessing. The ultrafine powder is the preferred raw material for the production of variousgreen and environmentally friendly inorganic magnesium hydroxide flame retardants. Ithas the triple function of flame retardant, smoke suppressant and filling, releases bindingwater when heated to decompose, and absorbs a large amount of latent heat to reduce thesurface temperature of the synthetic material it fills in the flame., It has the effect ofinhibiting the decomposition of polymers and cooling the generated combustible gases,and can be widely used for the flame retardation of engineering plastics, epoxy resin, rubber,wire and cable fillers, mining cable covers, cable accessories. It can replace aluminumhydroxide and has excellent flame retardant effect.
