In the quest for enhanced fire safety, the chemical industry continuously seeks advanced materials and synergistic formulations. Anhydrous Zinc Borate (CAS 12767-90-7) is a remarkable inorganic flame retardant that not only offers excellent performance on its own but also demonstrates powerful synergistic effects when combined with other common flame retardant additives. As a leading manufacturer and supplier from China, we offer high-purity Anhydrous Zinc Borate, enabling manufacturers to achieve superior fire resistance and smoke suppression in their polymer products.

The effectiveness of flame retardants is often amplified when used in combination, a phenomenon known as synergy. Anhydrous Zinc Borate is a prime example of a versatile additive that exhibits strong synergistic properties with several other flame retardant systems. When formulated correctly, these combinations can deliver superior fire performance compared to individual components. For procurement managers, understanding these synergistic relationships is key to optimizing material costs and performance.

One of the most well-documented synergistic partnerships for Anhydrous Zinc Borate is with antimony trioxide (Sb2O3). In halogen-containing systems, zinc borate can enhance the effectiveness of antimony trioxide, allowing for lower loadings of both while maintaining or improving flame retardancy. Zinc borate helps catalyze the formation of char and creates a protective glassy layer, while antimony trioxide works in the gas phase by scavenging radicals and producing antimony halides. This combined action significantly improves the overall flame-retardant performance. For those looking to buy flame retardants, this synergistic combination offers a robust solution for stringent fire safety requirements.

Equally important is the synergy observed when Anhydrous Zinc Borate is combined with inorganic hydroxide flame retardants, such as alumina trihydrate (ATH) and magnesium hydroxide (MDH). In halogen-free systems, these combinations are particularly valuable. When exposed to high temperatures, zinc borate releases water vapor, which cools the material and dilutes flammable gases. Simultaneously, the water released by ATH and MDH contributes to the cooling effect and char formation. The presence of zinc borate can further improve the quality of the char layer and, in some cases, forms a porous ceramic barrier with ATH at elevated temperatures, enhancing insulation and limiting heat and mass transfer. This makes them ideal for applications requiring excellent fire and smoke control, such as in cables, construction materials, and electronics. We, as a dedicated China manufacturer, provide high-quality zinc borate that is perfectly suited for these synergistic applications.

The benefits of these synergistic formulations extend beyond just flame retardancy. They also contribute to improved smoke suppression. As smoke inhalation is a major cause of fatalities in fires, flame retardants that minimize smoke production are highly sought after. Anhydrous Zinc Borate, with its ability to promote charring and release water, plays a crucial role in creating low-smoke formulations. This is especially important for materials used in enclosed spaces like buildings and vehicles. For companies aiming to buy advanced flame retardant packages, incorporating zinc borate with other synergists is a strategic move.
