Zinc borate is an environmentally friendly non halogen flame retardant. According to its composition (XZnO.YB2O3.ZH2O), there are more than ten kinds of FB flame retardants. The most commonly used variety is this product - 3.5 water zinc borate, also known as ZB - 2335 flame retardant. This product is non-toxic, low water solubility, high thermal stability, small particle size, small proportion, good dispersion and other characteristics, as an efficient flame retardant, is widely used in plastics, rubber, coatings and other fields.
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.
