HF-600A Halogen-Free Phosphorus-Nitrogen Flame Retardant for TPU TPE Cables - 2-5μm Particle Size, ≥20% Phosphorus Content
HF-600A is a phosphorus-nitrogen (P-N) synergistic flame retardant specifically engineered for thermoplastic polyurethane (TPU) and thermoplastic elastomers (TPE). This halogen-free solution combines char-forming and gas-phase flame inhibition mechanisms to deliver superior fire protection while maintaining critical cable performance properties.
