Our phosphorus-based intumescent flame retardant (IFR) is an advanced halogen-free solution designed to meet modern safety and environmental standards. Composed primarily of phosphorus and nitrogen, it operates through a synergistic mechanism: when exposed to heat, it forms a dense, expanded carbonaceous char layer that shields the underlying material by insulating against oxygen and heat, while effectively suppressing smoke and toxic gas emissions. This intumescent action—driven by acid source, carbon source, and gas source components—ensures exceptional fire resistance (achieving UL94 V-0 ratings) with minimal environmental impact. Ideal for thermoplastics like PP, PE, and TPU, this retardant excels in applications ranging from injection molding to extrusion and coatings. It boasts high thermal stability (withstanding processing temperatures up to 220°C), low smoke density, and no corrosive halogen by-products, aligning with EU RoHS and REACH regulations . Additionally, it preserves mechanical properties such as tensile strength and impact resistance, ensuring both safety and material integrity. ?Key Advantages:?? ?Eco-Friendly:??
