Zinc Borate
Category : Inorganic chemicals/Inorganic salts
CAS NO : 1332-07-6 EC NO : 215-566-6 MF : ZnHBO3 MW : 125.2261 Specification : 99% min Packing : Packing: 25 kg bag Product description : Zinc Borate Flame Retardant ZB Molecular Formula: ZnHBO3 Molecular Weight: 125.23 CAS: 1332-07-6 EINECS: 215-566-6 Appearance: White powder Properties: Zinc borate(3.5H2O),zinc borate(7H2O),zinc borate(modified) and Anhydrous zinc borate are the four main types of zinc borate. white powder.Density is 2.67g/cm3. The melting point is 980℃.The refractive index is 1.58.Insoluble in water, alcohol. but soluble in chlorhydric acid, sulfuric acid. Application: Zinc borate is inorganic addition flame retardant. it has good hot stability, stops buring and vanishes smokings. It can replace antimonous oxide but also be used with other inorganic flame retardant. Widely used in rubber, plastic, wood, cable, coating, etc.Zinc borate,modified can completely replace zinc borate. It have the advantage of lower price, better effect stops buring and vanishes smokings.
