Introduction
YIMA SFR-Si927 is an organosiloxane flame retardant synergist . It improves the flame retardant rating and aging resistance of PC.
1、Exhibits excellent compatibility with PC resin. When combined with sulfonate or organic phosphorus flame retardants, it imparts superior flame retardancy to PC materials. Recommended addition ratio: 1-3% by weight.
2、Enhances processability, improves dispersion with other inorganic fillers, and boosts flame retardant performance in high-filler PC systems.

| SFR-Si927 | PC | 1-35 |
Usage Instructions
• Actual dosage may vary depending on screw configuration, processing temperature, and specific requirements.
• For better dispersion, SFR-Si927 can be pre-compounded into a high-concentration masterbatch before processing to achieve optimal flame retardant effects.
