Applications:

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 chemical properties, Zinc borate is also used on anti-corrosion, infra red absorption, fungicide for wood preservation etc fields.

 

Storage: Be stored in a clean and dry storehouse, don't to let it be rained on, no mix storage and transportation with acids is allowed
