Brief: Need quick answers about practical use? This video highlights the essentials. Watch as we demonstrate the properties and applications of White Non Halogen TF-201 Ammonium Polyphosphate Phase II, an environmental flame retardant. You'll see how it functions as an acid source in intumescent coatings for steel, wood, and textiles, and learn about its key specifications and decomposition behavior under heat.
Related Product Features:
  • Acts as a non-halogen flame retardant and acid source in intumescent mechanisms.
  • Decomposes to polymeric phosphoric acid and ammonia when exposed to fire or heat.
  • Available in two models: TF-201 with D50 15-25µm and TF-201S with D50 <12µm particle size.
  • Features high P2O5 content (≥71% for TF-201, ≥70% for TF-201S) and nitrogen content (≥14%).
  • Has a high decomposition temperature above 275°C, ensuring thermal stability.
  • Exhibits low solubility in water (<0.45% for TF-201, <0.7% for TF-201S at 25°C).
  • Suitable for applications in steel structure, wood, and textile intumescent coatings.
  • Maintains a neutral pH range (5.5-7.5) and low moisture content (<0.25%).
Ερωτήσεις:
  • What is the primary function of TF-201 Ammonium Polyphosphate Phase II?
    TF-201 acts as a non-halogen flame retardant that serves as the acid source in intumescent systems. When exposed to fire or heat, it decomposes to form polymeric phosphoric acid and ammonia, which helps create a protective char layer that insulates the material and slows down combustion.
  • What are the main application areas for this flame retardant?
    This product is primarily used in intumescent coatings for steel structures, wood coatings, and textile coatings. It provides effective fire protection by forming an insulating char layer when subjected to high temperatures.
  • What is the difference between TF-201 and TF-201S models?
    The main difference lies in the particle size distribution. TF-201 has an average particle size (D50) of 15-25µm, while TF-201S has a finer particle size of <12µm. Both share similar chemical properties including P2O5 content (≥71% vs ≥70%), nitrogen content (≥14%), and decomposition temperature (>275°C).
  • How does the decomposition temperature affect its performance?
    With a decomposition temperature above 275°C, TF-201 maintains stability under normal processing conditions while activating at appropriate temperatures during a fire. This ensures the flame retardant mechanism engages effectively when needed without premature degradation during manufacturing or use.
