For manufacturers in the plastics, rubber, and coatings industries, achieving superior fire safety is paramount. Zinc Borate (CAS 1332-07-6) stands out as a highly effective inorganic additive that provides both flame retardancy and smoke suppression. As a premier Zinc Borate manufacturer based in China, we understand the critical factors you consider when sourcing this essential chemical. This guide aims to help you make an informed purchase decision, ensuring you acquire the best Zinc Borate for your specific applications.

Understanding Zinc Borate's Role as a Flame Retardant Synergist

Zinc Borate is a multi-functional additive. Its unique chemical structure allows it to perform effectively in both halogen-based and halogen-free flame retardant systems. When incorporated into polymers, it works by:

• Promoting Char Formation: During a fire, Zinc Borate facilitates the creation of a stable char layer on the material's surface. This layer acts as a physical barrier, insulating the underlying material from heat and oxygen, thereby slowing down combustion.
• Releasing Water of Hydration: At elevated temperatures, Zinc Borate releases its bound water. This process absorbs heat energy from the fire, effectively cooling the material and further inhibiting combustion.
• Smoke Suppression: A significant benefit of Zinc Borate is its ability to suppress smoke generation. This is crucial for improving visibility and escape times during a fire, enhancing overall safety.

Key Properties to Consider When You Buy Zinc Borate

When looking to purchase Zinc Borate, manufacturers should pay close attention to the following specifications, which we consistently provide:

• Purity: Our Zinc Borate typically offers a purity of ≥99.0%, ensuring maximum efficacy in your formulations. High purity guarantees consistent performance and fewer unwanted side reactions.
• Appearance: Available as a fine white or light yellow powder, our Zinc Borate is easily dispersible in various polymer matrices, facilitating homogeneous incorporation.
• Particle Size: Controlled particle size distribution is essential for good dispersion and effective performance. We offer refined powders suited for demanding applications.
• Thermal Stability: With a melting point of 980°C, our Zinc Borate can withstand typical processing temperatures of most plastics and rubbers without premature decomposition.

Applications Where Zinc Borate Excels

The versatility of Zinc Borate makes it indispensable across numerous industries. If you are a manufacturer seeking to buy Zinc Borate in China, consider its application in:

• Plastics: Widely used in PVC, PE, PP, ABS, polyamides, and epoxy resins for applications like wires, cables, flooring, and automotive parts.
• Rubber: Enhances the flame retardancy of natural and synthetic rubbers used in hoses, belts, and seals.
• Coatings: Incorporated into intumescent coatings to provide excellent fire protection and smoke suppression for construction materials.
• Textiles and Paper: Used to impart flame retardancy to fabrics, wallpaper, and paper products.
