Polyvinyl Chloride (PVC) is a widely used polymer in critical applications like wires and cables, flooring, and construction materials. Its inherent flame resistance can be significantly enhanced with the addition of specialized flame retardants. Zinc Borate (CAS 1332-07-6) is an exceptionally effective inorganic additive that improves PVC's fire safety profile, primarily through its flame retardant and smoke suppressant properties. As a leading Zinc Borate supplier, we provide insights into how PVC manufacturers can leverage our product for superior performance and safety.

Why Zinc Borate is Ideal for PVC Applications

PVC formulations benefit immensely from the incorporation of Zinc Borate due to its specific characteristics:

  • Enhanced Flame Retardancy: Zinc Borate acts as a potent flame retardant synergist in PVC, working effectively with other additives commonly used in PVC compounding, such as antimony trioxide and chlorinated paraffins. It promotes char formation, creating a protective barrier that slows down flame spread and reduces heat transfer.
  • Superior Smoke Suppression: A critical advantage of Zinc Borate in PVC applications, particularly in cables and building materials, is its ability to significantly suppress smoke generation during combustion. This improves visibility and safety during fire emergencies.
  • Anti-Dripping Properties: During thermal decomposition, Zinc Borate can help to promote a more coherent char structure, which reduces the dripping of molten polymer during a fire. This limits the spread of flames to other materials.
  • Improved Electrical Properties: In wire and cable applications, Zinc Borate can contribute to better electrical insulation properties and reduce the risk of tracking and arcing.
  • Synergistic with Other Additives: It works exceptionally well with common PVC stabilizers and flame retardant systems, allowing for optimized formulations and cost-effectiveness.
