HF-T300 Halogen-Free Intumescent Flame Retardant P-N Synergistic System UL94 V-0 with 220°C Processing Temperature
HF-T300 is an advanced phosphorus-nitrogen (P-N) synergistic intumescent flame retardant that forms a protective carbon layer to isolate oxygen and heat sources. This halogen-free solution outperforms traditional ammonium polyphosphate (APP) systems with lower loading requirements and higher processing temperatures up to 220°C.
| Resin Type | HF-T300 Addition | UL94 Flame Retardant Grade |
|---|---|---|
| PP | ≥20% | V-0 (1.5mm) |
| HDPE | ≥32% | V-0 (1.5mm) |
| PP + 30%GF | ≥22% | V-0 (1.5mm) |
| TPE | ≥32% | V-0 (3.0mm) |
| TPU | ≥25% | V-0 (1.5mm) |
- Achieves UL94 V-0 at reduced loadings compared to APP systems
- Forms stable intumescent char layer resistant to temperatures above 500°C
- 30% higher Limiting Oxygen Index (LOI) than halogenated alternatives
- Thermal stability up to 220°C (TGA onset)
- Compatible with injection molding, extrusion (twin-screw recommended), and compression molding
