SFR-4D Special Flame Retardant for EPDM Rubber Extrusion

Specifications

Compliance with Standards

SFR-4D adheres to global safety regulations, including UL94 V-0 (for rubber compounds), EU RoHS/REACH, and NFPA 701. Its halogen-free formulation ensures low smoke and toxic fume emissions during combustion, making it suitable for environmentally sensitive applications.

Applications

1. Automotive Industry: Flame-retardant EPDM rubber seals, gaskets, and hoses.
2. Construction Materials: Fire-resistant EPDM rubber sheets for roofing, waterproofing, and building interiors.
3. Electrical Insulation: EPDM rubber components for high-voltage cables and electrical enclosures.
4. Public Transportation: EPDM rubber parts for trains, buses, and subway systems.

Advantages and Features

1. High-Efficiency Flame Retardancy: Achieves UL94 V-0 rating with a low dosage (10–15 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 220–300°C, ideal for high-temperature EPDM extrusion processes.
4. Process Compatibility: Easy to blend with EPDM rubber via standard extrusion methods, ensuring consistent quality and processing efficiency.
