Features and Application
Zinc Borate is one environmental-friendly halogen-free flame retardant. There are
some formulations of xZnO.yB2O3.zH2O, in which Zinc Borate with 3.5 hydrate is
called ZB - 2335 (2ZnO.3B2O33.5H2O)is the most common used grade. It has
owned some excellent properties on non-toxicity, slight solubility in water, good
thermal stability, fine particle size, low specific gravity, great free-flowing etc.
1. Zinc borate can be used as multi-functional synergistic additives with antimony
oxide or other halogenated flame retardants to significantly improve the flame
retardant performance, remove smoke emission and adjust the balance on chemical,
mechanical, electrical etc properties.
2. As environmental protection substitute to replace current Antimony Oxide or
halogen flame retardants, Zinc borate is directly used in PVC, PE, Polyolefin, Epoxy Polyamide etc resins and rubber process. Moreover, it is widely used in textile, fiber, 
floor, leather, wall paper, carpet, paint etc decorative materials to improve flame
retardant performance.
3. Base on its anti static properties, zinc borate is widely used in mining plastic
material, and used on anti-corrosion, infra red absorption, fungicide for wood
preservation etc fields.
