Zinc borate Commodity Name: Zinc Borate (3.5H2O) , ( Firebrake ZB 2335) Molecular Formula: 2ZNO, 3B2O3, 3.5H2O The Zinc Borate produced by our factory is also called FB Fire Retardant, ZB-2335 Fire Retardant or Firebrake ZB. Property: White crystal powder, without poison, flavor and corrosiveness. Doesn't dissolve in water and other organic solvent, is easy dissolved in hydrochloric acid & sulfuric acid, etc. Good thermal stability, small granule size, less specific gravity and easy dispersed. Good miscibility with most of the polymer. Fewest smoke when burning, excellent performance in inflaming retarding Certificate Of Analysis:Item Index Zinc Borate % 99 Apperance White crystal powder Boron Oxygenation (B2O3) % 48.0 í+ 3 Zinc Oxygenation (ZnO) % 38.0 í+ 2 Moisture (H2O) % í_1 specific gravity g/cm3 2.67 Residues on 350 meshú¿350-+ú¬% í_0.5 Temp of loss crystal water íµ 350í+50 Refractive index 1.58 Melting point íµ 980 Pb % 0.03 max Fe % 0.06 max As % 0.06 max Packing Inner plastic film with PP woven bags outside Net weight 25 kg/ Bag Loading Quantity 20MT or 22MT / 20'FCL 25KGS BAG
