Description
Zinc borate is an inorganic compound with the chemical formula ZnB4O7. It is a white, crystalline powder that is insoluble in water and most organic solvents. Zinc borate is a boron-based flame retardant and smoke suppressant with several applications. Here are some key aspects and uses of zinc borate: Flame Retardant: Zinc borate is primarily used as a flame retardant and smoke suppressant in various materials and applications. It can be added to polymers, plastics, rubber, textiles, coatings, and other materials to enhance their fire resistance properties. Zinc borate releases water when exposed to heat, which dilutes combustible gases and inhibits flame spread. Smoke Suppressant: Zinc borate helps reduce smoke and toxic gas emissions during fires. By releasing water vapor and capturing volatile organic compounds, it can lower the smoke density and improve visibility in fire situations. Anti-Corrosion and Anti-Fungal Agent: Zinc borate exhibits anti-corrosion and anti-fungal properties, making it useful in coatings, paints, and wood preservatives. It can protect surfaces from degradation caused by moisture, fungi, and UV radiation. PVC Stabilizer: Zinc borate can act as a stabilizer and lubricant in the processing of polyvinyl chloride (PVC). It helps improve the melt flow, reduce friction, and prevent degradation of PVC during extrusion and molding processes. Ceramic Industry: Zinc borate finds applications in the ceramic industry as a flux and opacifier. It can lower the melting point of ceramics, improve glaze adhesion, and provide opacity or whiteness to ceramic products. Adhesives and Sealants: Zinc borate is utilized in adhesives and sealants as a flame retardant additive. It helps meet fire safety regulations and improve the fire resistance of these products. Overall, zinc borate is primarily known for its flame retardant and smoke suppressant properties. Its applications extend to various industries, including plastics, coatings, textiles, ceramics, and adhesives, where fire resistance and smoke suppression are desired.
