The substitution of antimony trioxide

highly-efficient antimony flame retardants is taking the antimony and Imidazole derivatives as the ligand, being a synthesis of functional groups of metal complexes. It can improve the catalytic efficiency of antimony bromide retardants and replace the antimony trioxide. The effect is better than others. It could be used in environmental protection areas for the good dispersivity and does not contain heavy metals such as halogen and Pb.it reaches compliance with EU environmental directives and regulatory requirements ROHS.
