Char-forming additive

Our char-forming agent is a high-performance, halogen-free solution designed to maximize flame retardancy by leveraging synergistic effects with various flame retardant systems. When combined with acid sources like ammonium poly-phosphate (APP) or phosphorous-based retardants, it triggers efficient intumescent action: under heat exposure, it rapidly forms a stable, expanded carbonaceous layer that shields the material by isolating oxygen and heat, while significantly reducing smoke and toxic gas emissions. This synergy enables up to 30% reduction in traditional retardant usage while achieving UL94 V-0 standards .

Compatible with PP, PA, PBT, and bio-polymers like PLA, the agent enhances char layer density and mechanical strength without compromising processability. Its ultra-low moisture absorption (<0.3%) and high decomposition temperature (≥300°C) ensure durability in demanding applications. Ideal for wires, cables, and electronic housings, it offers a sustainable path to superior fire safety .
