Zinc Borate is used as a flame retardant and smoke suppressant for wide range of plastics, rubbers, paper and textiles. It can replace antimony oxide as a synergist in plastics and rubber to enhance the activity of primary flame retardants byreleasing the radicals. It is also used in paints, adhesives, pigments and ceramic industries. It also acts as an antifungal agent and as a soil amendment to improve the vigor of plants.
