Zinc borate has been used as a bactericidal and preservative for a long time, and has the flame retardant properties of wood. Zinc borate is toxic to cells and is also an inhibitor of enzymes. Because the activity of enzymes in the bacteria is blocked, it inhibits the growth of fungi, and has a wide range of effects on organisms that damage wood fibers, such as fungi such as white rot bacteria and brown rot bacteria, and termites and other insects that harm the plate.

Zinc borate is an environmentally friendly non-halogen flame retardant, which is non-toxic, low water-soluble, high thermal stability, small particle size, small specific gravity and good dispersion. As a high-efficiency flame retardant, it is widely used in plastics, rubber, coatings and other fields. It is used for waterproofing, flame retardant, ceramic glaze, coating anti-mildew and sterilization of fabrics.
