Applications  :

1. Zinc Borate can be used as a kind of multi-functional synergistic additive of Antimony oxide and other halogen flame retardant ,can improve the nature of flame retardant effectively, to reduce the smoke produced when combustion, and can adjust rubber products chemical machinery, electricity and other aspects of performance.
2.  As the partial or completely environmental protection substitute of containing halogen and other flame retardants , zinc borate is being directly applied to a wide range of plastics and rubber processing, such as PVC, PE, PP, enhance polyamide, PVC resin, polyphenylene ethylene, epoxy resin, polyester resin acid ethylene and natural rubber, styrene butadiene rubber, chloroprene rubber. It can also be applied to the production of paper, fiber fabric, decorative panels, floor leather, wallpaper, carpet, ceramic glaze, fungicides, and paint production in order to improve flame retardants performance.

 3.  Based on other natures, zinc borate, can also be used for anti-corrosion, far-infrared absorption, and timbers anti-pest and anti-bacteria handle and other fields.
