one. Zinc borate can be utilised as multi-functional synergistic additives with antimony oXiHu (West Lake) Dis.de or other halogenated flame retardants to considerably increase the flame retardant functionality, eliminate smoke emission and alter the equilibrium on chemical, mechanical, electrical and so on homes.
2. As environmental protection substitute to replace existing Antimony OXiHu (West Lake) Dis.de or halogen flame retardants, Zinc borate is right utilised in PVC, PE, Polyolefin, Epoxy PoEPTmide and so on resins and rubber approach. Furthermore, it is broadly utilised in textile, fiber, floor, leather, wall paper, carpet, paint and so forth ornamental components to enhance flame retardant functionality.
3. Base on its chemical properties, Zinc borate is also used on anti-corrosion, infra purple absorption, fungicide for wood preservation and so forth fields.
