Applications of Brominated SBS

Brominated SBS is primarily used as a flame retardant in expanded polystyrene (EPS) and extruded polystyrene (XPS), particularly for thermal insulation boards and other polystyrene foam applications.

Core Advantages of ST-970 Brominated SBS

    • High Molecular Weight: The polymeric structure helps reduce migration compared with conventional low-molecular-weight brominated flame retardants.
    • Good Thermal Stability: Suitable for EPS/XPS processing conditions requiring good thermal stability at elevated temperatures.
    • Low Blooming Tendency: Helps minimize surface migration and frosting during processing and long-term use.
    • HBCD Alternative: Designed for EPS/XPS applications where a polymeric brominated flame retardant is required.

Packaging, Storage & Global Logistics

  • Packaging Options: 15kg/bag, 500kg/bag, or customized jumbo bags according to your specific requirements.

  • Storage Requirements: Store this Brominated SBS in a cool, dry, and well-ventilated area. Keep the packaging tightly sealed to prevent moisture from affecting the EPS flame-retardant performance.

  • Shipping Information: Not regulated for transport. Senthos provides efficient global logistics, ensuring a stable supply of high-quality Brominated SBS to your facility.
