Its characteristics are that it has good hot stability, and not only stops buring and vanishes smokings but also be used with other inorganic flame retardant. It is used in epoxy resin, unsaturated polyester, polyurethane, etc. And it is widely used in rubber, plastic, cable, wood,etc.4.Packing and store  Packing brown paper double deck tectorial bag, and net weight per bag is 25kg.store storing in dry, ventilated and moistureproof conditions.zinc borate 1.Appearance white powder 2.Cas no.;12536-65-1 3.Molecular weight 434.62 Flame retardant-Zinc Borate 1.Basic Index Molecular formula2ZnO·3B2O3·3.5H2OMolecular weight435.4Appearancewhite powderMelting point980°C 2.Specification Item/GradeZinc borate ( 2ZnO.3B2O3 3.5H2O)Excellent gradeFirst gradeWhiteness9995Surface water % ≤0.51.0Particle size, um3-53-5ZnO, %37.0-40.0B2O3 , %45.0-48.0Loss on ignition,%13.5-15.5Fineness (Residue on 45um sieve ), %  ≤0.1Specific gravity, g/cm32.67Melting pointoC;980Temp. of dehydration oC>320Refractive index1.58 3.Application Field      Flame Retardant ZB is inorganic addition flame retardant.
