Introduction of Zinc Borate
Zinc borate is an inorganic compound, a borate of zinc. It is a white crystalline or amorphous powder insoluble in water. Its toxicity is low. Its melting point is 980 °C.
Zinc Borate is environmental protection non-halogen flame retardants, According to the difference of composition (XZnO.YB2O3.ZH2O), FB flame retardant has more than ten varieties. Through SGS testing, zinc borate is environmental protection type non-halogen flame retardants. This product is non-toxic, low-water-soluble, high heat stability, small particle size, proportion small proportion, good dispersion characteristics.
Application
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.
