Application:
Zinc Borate is an environmentally friendly substitute for halogen-containing flame retardants.It is widely and directly used in the processing of plastics and rubber. It can also be applied in the production of paper, fiber fabrics, decorative panels, floor leather, wallpaper, carpets, ceramic glazes, fungicides, and coatings to improve flame retardant performance. It can also be used in fields such as anti-corrosion, far infrared absorption, and wood pest and bacterial prevention treatment.
