Product Overview
HF-600B is a phosphorus-nitrogen (P-N) synergistic flame retardant specifically engineered for thermoplastic polyurethane (TPU) and thermoplastic elastomers (TPE). Utilizing dual charring and gas-phase mechanisms, it delivers superior flame retardancy while maintaining critical material properties for cable and connector applications.
