What Problems Can Hydroxyphenyl Siloxane Resin SFR-SI907 Solve in PC Modification?

YIMA SFR-Si907 is a high-efficiency silicone-based flame retardant synergist widely used in engineering plastics such as PC and PC/ABS. The recommended addition level is 0.5-1.0%, and it must be used in combination with a primary flame retardant. Its main advantages include improving the flame retardant rating, promoting char formation, suppressing smoke, and having minimal impact on material transparency.

Typical Performance Improvements with SFR-Si907:

Flame Retardancy: UL94 rating improved by 1-2 levels (e.g., from HB to V-1 or V-0).

Thermal Stability: Heat deflection temperature increased by 5-15°C.

Mechanical Properties: Impact strength retention rate ≥90%, with potential improvement of 5-10% in some systems.

Smoke Suppression: Smoke density reduced by 20-40%, enhancing environmental friendliness during combustion.
