Materialize characterInnocuity,Indissoluble in water and ecumenical organic impregnant,thermal stability is well,granularity is very small,dispersivity powerful, smoking formation tiny when combustion,fire retardant great.
Application: wide use in plasticsrubberpaintinflaming retarding dopeceramicselectrical insulating material,electronic goods crustwirecable and so on.Especially serve for flame retardant andantismoke agent, coordinate with halogen flame retardant is better,can serve for flame retardant alone,also can collective use with diantimony trioxide,it can instead 50%-80% diantimony trioxide,and can to be anti-corrosive primer instead venomous zinc chromate,offen to be glaze in ceramics,and can to be wood preservative,moreover Zinc Borate is radial ply tire special complete a set raw material.
