HF-T912 DOPO Derivative Flame Retardant Halogen-Free Phosphorus-Based 14% P Content 110-130°C Melting Point for Epoxy PA PC UL94 V-0
HF-T912 is a novel DOPO derivative flame retardant (CAS: 1631149-46-6, C₂₂H₂₄P₂O₄) designed for high-performance halogen-free applications. This phosphorus-based compound combines gas-phase radical quenching and condensed-phase char formation mechanisms, making it ideal for engineering resins in electronics and electrical applications.
- Dual mechanism: PO* radical scavenging + char layer formation (>450°C)
- Achieves UL94 V-0 at 5-12% loading in epoxy/PA
