Zinc Borate: Multifunctional Flame Retardant And Smoke Suppressant For Plastics, Wood, And Industrial Applications

Key Features:

• Chemical Formula: 2ZnO · 3B₂O₃ · 3.5H₂O
• Molecular Weight: ~434.66 g/mol
• Appearance: Fine, white powder
• Decomposition Temperature: ~290°C (554°F)
• Solubility: Insoluble in water but can be dissolved in acids

Applications:

1. Flame Retardant in Plastics and Polymers:

   • Commonly used in PVC, polyolefins, nylons, and other thermoplastics to improve fire resistance.
   • Acts as a smoke suppressant and prevents dripping during combustion.

2. Wood and Cellulose-Based Products:

   • Used in wood composites, plywood, fiberboard, and other cellulose materials to provide termite resistance and act as a preservative against fungi and mold.

3. Coatings and Paints:

   • Added to paints, coatings, and varnishes to enhance their flame retardancy properties.

4. Ceramics and Glass Production:

   • Used as a flux in the production of ceramics and glass to reduce melting temperatures and enhance product durability.

5. Rubber and Textile Industry:

   • Incorporated into rubber compounds, textile coatings, and upholstery to impart flame retardant properties.

Advantages:

• Multifunctional Flame Retardant: Provides both fire resistance and smoke suppression.
• Low Toxicity: Safe for use in many applications and environmentally friendly compared to other flame retardants.
• Thermal Stability: Remains effective at high temperatures.
• Synergistic Effects: Enhances the effectiveness of other flame retardants, such as antimony trioxide and aluminum hydroxide.

Safety and Handling:

• Handling Precautions: Avoid inhaling dust; use personal protective equipment (PPE) like masks and gloves. Ensure adequate ventilation in work areas.
• Storage: Store in a cool, dry place, away from incompatible materials like acids.

Regulatory Information:

• Generally recognized as safe for use in a wide range of industrial and consumer applications. However, local regulations regarding the handling and disposal of zinc borate should be followed.

Packaging:

• Available in 25 kg bags, bulk bags, or customized packaging according to customer requirements.
