Zinc Borate is an inorganic white crystalline powder insoluble in water. It is widely used as a flame retardant in plastics & cellulose paper, rubbers, fibers and textiles. It is also used in adhesives, pigments and paints. As a flame retardant, this powder can replace antimony(III) oxide as a synergist in halogen-based & halogen-free systems. Moreover, in electrical insulator Zinc Borate it suppresses arcing and tracking. The toxicity of this powder is low and 980 °C melting point.
