  • What are the primary applications of this ammonium polyphosphate flame retardant?
    It is used to prepare high-efficiency intumescent coatings for wood, buildings, ships, and cables; as a main flameproof additive in plastics, resins, and rubber; in powder extinguishing agents for large-area fires; and for textile coatings.
  • What is the key advantage of the small particle size in TF-201S?
    The small average particle size (D50 < 12µm) ensures better dispersion in formulations, leading to more uniform flame retardancy and improved performance in coatings and composite materials.
  • How does the low viscosity of this flame retardant benefit polyurethane applications?
    The low viscosity (<20 mpa.s in 10% aqueous solution) allows for easier mixing and processing in polyol suspensions and polyurethane systems, enhancing workability without compromising flame retardant efficacy.
