SFR-4A Special Flame Retardant for Chloroprene Rubber

Specifications

Compliance with Standards

SFR-4A adheres to international safety standards, including UL94 V-0 (for rubber compounds), EU RoHS/REACH, and NFPA 701. It is halogen-free, ensuring low smoke and toxic fume emissions during combustion, making it suitable for environmentally sensitive applications.

Applications

1. Seals and Gaskets: Flame-retardant chloroprene rubber parts for automotive, aerospace, and industrial machinery.
2. Wiring and Cables: Insulating materials for high-temperature and fire-resistant cables.
3. Protective Gear: Components for firefighting suits, gloves, and other safety equipment.
4. Construction Materials: Fire-resistant rubber sheets for building interiors and transportation systems.

Advantages and Features

1. High-Efficiency Flame Retardancy: Achieves UL94 V-0 rating with a low dosage (15–25 phr), minimizing impact on rubber’s mechanical properties.
2. Environmental Safety: Halogen-free formulation reduces corrosive gas emissions and environmental harm.
3. Thermal Stability: Maintains performance at 250–300°C, ideal for high-temperature applications.
4. Process Compatibility: Easy to blend with chloroprene rubber via standard mixing methods, ensuring consistent quality.
