The melting point is 980℃.The refractive index is 1.58.Insoluble in water, alcohol. but soluble in chlorhydric acid, sulfuric acid. Quality standard Zinc borate(3.5H2O) Item Index Appearance White powder B2O3 48.0%+-1.5% ZnO 37.0%+-1.5% Loss on ignition 13.5%-15.5% Free water min 1.0% Pass Mesh 325 min 1.0% USE:It is widely used in industry of rubber, plastic, fibre, paint, ceramic, medicine. Also used in producing of insulating material & products, rubber tapes & pipes, electrical cables & wires, germicide, mildew inhibitor, and many kinds of fire protection coatings. Good effect when used together with organic halide. The Zinc Borate can be used as fire retardant singly, also can be mainly used instead of stibous oxide; comparing with stibous oxide, the Zinc Borate is cheaper & no poison. The Zinc Borate acts the roles as frit in ceramics, acts the roles as the matching material in Radial tyre, also acts the roles as the preservative in wood industry too. In a word, it is a ideal inorganic fire retardant with function of environment protection.

• Uses :

  It is as flame retardant widely used in rubber, plastic, cable, wood,etc
