Environmental-Friendly Flame Retardant Synergist – SF-900
SF-900 is a halogen-free environmental flame retardant based on phosphorus and nitrogen. It complies with EU RoHS Directive and REACH regulations.
SF-900 features excellent thermal stability, water insolubility, non-hygroscopicity, low density of flame-retardant products, low smoke emission and low mold corrosion.
Properties
- Appearance: White powder
- Density: ~1.9 g/cm³
- Moisture content: ≤0.5%
- Whiteness: ≥93%
- Phosphorus content: 12–14%
- Average particle size: ~10 μm
- pH value: 6.5–7
- Decomposition temperature: ≥380 ℃
- Conductivity: ≤500 μS/cm
Safety & Toxicity
SF-900 is non-toxic. As it is a fine powder, proper protection is recommended during processing.
Applications
SF-900 is melamine-free and can be used in PA6 and PA66 systems to replace MPP.It has higher temperature resistance but slightly lower efficiency than MPP.In PA systems, better performance can be achieved by properly increasing the dosage of aluminum diethylphosphinate (ADP).
Recommended ratio:Aluminum diethylphosphinate : SF-900 = 2 : 1
