Zinc Borate is a flame retardant and smoke suppressant additive widely used in various industries. It is commonly incorporated into materials such as PVC, PP, PE, ABS, and Nylon. It offers fire resistance and smoke reduction. This compound is also effective in coatings, rubber, wires, cables, and wood products. It helps to prevent material degradation under high temperatures.

With a molecular formula of 2ZnO.3B2O3.3.5H2O, Zinc Borate provides dispersion and even particle distribution. It has a refractive index of 1.58 and a melting point of 980°C, making it fit for use in high-temperature environments. Zinc Borate also features a bulk density of 400-500 g/cm³ and electrical conductivity of less than 1500 μs/cm.

Qingdao Collect Chemical Co., Ltd., based in China, is the manufacturer, supplier, and trader of Zinc Borate.
