For procurement managers and R&D scientists in the chemical industry, sourcing high-quality Anhydrous Zinc Borate (CAS 12767-90-7) is crucial for ensuring the fire safety and performance of their polymer products. This inorganic flame retardant offers a host of benefits, including its halogen-free nature, high thermal stability, and smoke suppression capabilities. However, making an informed purchasing decision requires a thorough understanding of product specifications, key applications, and the importance of partnering with reliable suppliers, especially those based in China, a major global manufacturing hub for specialty chemicals.

When considering the purchase of Anhydrous Zinc Borate, several technical specifications are paramount. Firstly, the CAS number 12767-90-7 is essential for identifying the correct anhydrous form. Secondly, purity levels, typically expressed as ZnO and B2O3 content, are critical. Manufacturers often look for zinc oxide content around 41.0-46.0% and boron oxide content between 52.0-58.0%, with very low levels of impurities like lead, cadmium, and heavy metals. The physical form, usually a fine white powder with a specified particle size (e.g., 1-3 µm), dictates its dispersibility in various polymer matrices. Understanding these parameters is key to selecting a product that will perform optimally. As a reputable China supplier, we ensure our Anhydrous Zinc Borate meets these stringent quality benchmarks.

The applications of Anhydrous Zinc Borate are diverse, underscoring its importance across industries. It is widely used as a flame retardant and smoke suppressant in plastics such as PVC, PE, PP, and engineering polymers like Nylon and epoxy resins. Its effectiveness in rubber processing, textiles, coatings, and even in the production of paper and ceramic glazes further highlights its versatility. Procurement managers should consider the specific polymer system and processing conditions when evaluating Anhydrous Zinc Borate, looking for grades that offer optimal compatibility and thermal stability. For example, its high thermal decomposition temperature makes it ideal for high-temperature engineering plastics, ensuring the flame retardant remains active during demanding processing stages.

When it comes to procurement, especially for bulk quantities, identifying reliable suppliers is a critical step. China is a significant player in the global chemical market, offering competitive pricing and a vast manufacturing capacity for Anhydrous Zinc Borate. However, it is essential to partner with established manufacturers and suppliers who can guarantee consistent quality, adherence to specifications, and reliable delivery. Due diligence, including checking supplier certifications, requesting product samples for testing, and understanding their manufacturing processes, is highly recommended. We pride ourselves on being a trusted China manufacturer, offering transparent specifications, rigorous quality control, and dedicated customer service to ensure your procurement needs are met efficiently.

The synergistic effect of Anhydrous Zinc Borate with other flame retardants, such as antimony trioxide and alumina trihydrate, is another factor that buyers should consider. Formulating with these combinations can lead to enhanced fire safety and smoke reduction, often at lower overall additive loadings. This can result in cost savings and improved physical properties of the final composite material. When requesting quotes, it is beneficial to inquire about recommended synergistic formulations or to discuss your specific application challenges with the supplier's technical team.

In conclusion, sourcing Anhydrous Zinc Borate requires a focus on precise specifications, understanding its broad application potential, and selecting a trustworthy supplier. By prioritizing quality, performance, and reliability, businesses can effectively leverage this advanced flame retardant to meet demanding fire safety standards.
