On April 1, 2026, a halogen‑free flame retardant formulation for carboxylated styrene‑butadiene latex used in automotive nonwoven impregnation was officially released. It steadily achieves UL‑94 V‑0 rating, integrating low smoke, environmental friendliness and process compatibility, supporting safety upgrades of automotive interior materials. This phosphorus‑nitrogen intumescent system uses aluminum hypophosphite as the main flame retardant, combined with melamine cyanurate, zinc borate and modified aluminum hydroxide. It forms a dense char layer, suppresses smoke and prevents afterglow. The formula balances efficiency and flexibility, stable in aqueous latex. Pre‑dispersion, slow blending and gradient drying avoid thermal decomposition. Mechanical and aging resistance optimization paths are provided, complying with automotive requirements such as fogging and VOC. The halogen‑free solution addresses new energy vehicle interior safety demands, driving green, efficient and reliable material evolution, offering practical guidance for R&D and mass production.
