The incorporation of flame retardants into polymers is a critical aspect of modern material design, ensuring safety and compliance with industry standards. High-purity zinc borate, a versatile inorganic compound, plays a pivotal role in enhancing both the fire resistance and durability of numerous polymer systems. NINGBO INNO PHARMCHEM CO.,LTD. supplies this essential additive, enabling manufacturers to create safer and more robust products.

Polymers such as Polyvinyl Chloride (PVC), Polyethylene (PE), and Polypropylene (PP) are ubiquitous in our daily lives, found in everything from electrical cables and automotive parts to packaging and construction materials. However, these materials are inherently combustible, necessitating the use of flame retardants to mitigate fire risks. Zinc borate stands out as an effective and environmentally conscious solution for these applications.

When used in PVC formulations, zinc borate acts as a synergist, often in combination with other stabilizers and flame retardants. It contributes to char formation, which helps to prevent the material from dripping and spreading flames. Its thermal stability is crucial, as it ensures that the flame retardant properties are maintained even under processing conditions or during a fire event. This makes it a reliable inorganic flame retardant for plastics, particularly for demanding applications like wire and cable insulation.

In polyolefins like PE and PP, zinc borate enhances flame retardancy by releasing water vapor and forming a protective glassy layer. This mechanism effectively reduces the heat release rate and limits flame propagation. Furthermore, zinc borate can improve the mechanical properties of some polymers by acting as a reinforcing filler, contributing to overall material durability. The ability of zinc borate to provide multiple benefits, including fire resistance and improved processing, makes it a highly desirable additive for polymer manufacturers.

The efficacy of zinc borate in these polymers is well-documented. It is recognized for its ability to suppress smoke and prevent afterglow, critical safety features in many applications. As a halogen-free option, it aligns with the growing demand for sustainable and non-toxic materials. The market for high purity zinc borate flame retardant is robust, driven by the continuous need for safer and more performant polymer solutions.
