- Appearance: White to off-white crystalline powder
- Pureza: ≥98%
- Melting Point: 280-300°C
- Bromine Content: ~68%
- Storage: Keep in a cool, dry place away from direct sunlight
Aplicaciones clave
Octabromobisphenol-S is widely used as:
- Flame retardant additive in thermoplastics (e.g., ABS, HIPS, PP)
- Fire-resistant coating for electronic components
- Synergistic agent in construction materials
- Critical component in automotive and aerospace composites
Instrucciones de uso
- Dosificación: Typically 10-20% by weight in polymer matrices
- Mezclando: Blend evenly with base material at 150-180°C
- Seguridad: Use PPE (gloves, goggles, respirator) during handling
- Compatibilidad: Test with stabilizers like zinc borate for enhanced performance
Casos prácticos
1. Flame-Retardant Circuit Boards
A leading electronics manufacturer achieved UL94 V-0 rating by incorporating 15% Octabromobisphenol-S into epoxy resins, reducing peak heat release rate by 62%.
2. Fire-Resistant Building Panels
Combined with antimony trioxide (3:1 ratio), the additive enabled PVC-based panels to meet ASTM E84 Class A standards while maintaining mechanical strength.
