Composition：magnesium phosphite

Chemical formula：MgHPO₃

Application：Magnesium phosphite is a new type of inorganic phosphorus environment-friendly halogen-free flame retardant, which plays a flame retardant role by the mechanism of carbon formation and expansion. It can partially replace ADP and PAPP in polyamide and polypropylene, and maintain the excellent physical properties of the substrate. This product is white powder, high thermal stability, slightly soluble in water, non-toxic, does not contain halogen and heavy metals, in line with the EU environmental protection law requirements.
