Product application
1, zinc borate can be used as a multifunctional synergistic additive for antimony oxide or other halogen flame retardants, which can effectively improve the flame retardancy, reduce smoke production and adjust the physical, mechanical and electrical properties of rubber and plastic products.
2, zinc borate is widely used in PVC materials, such as carpet, conveyor belt, wire and cable, also used in flame retardant engineering plastics, aluminum hydroxide and magnesium hydroxide with halogen such as PE, PP, ABS etc., are also used in the thermal expansion coefficient of coating, ceramic glaze, fungicide, wallpaper, opal glass in the field of.
3, zinc borate is used in PVC, PE, PP and other wood materials as antibacterial agents, prevention of corruption fungi and termites. 4. It is suitable for wire and cable and other fields that require small processing particle size.
