Organophosphorus Flame Retardant Emulsion for Textile
Aqueous emulsion form of the halogen-free organophosphorus flame retardant for viscose fiber and textile applications. Available at 20% and 40% solid content, the stable nano-emulsion (particle size ~450 nm) offers easier handling, accurate dosing, and uniform dispersion in spinning dopes or finishing baths compared to the solid grade. Shares the same active chemistry as the solid form — modified thiophosphate ester, APEO-free, halogen-free — delivering durable flame retardancy with no adverse effect on whiteness, dyeability, or downstream textile processing. Ideal for operations preferring liquid handling or requiring ready-to-use FR concentrate.
