TY-423 is a type Ⅱ ammonium polyphosphatase ((NH4PO3)n) product with high degree of polymerization ≥1000 without complex and relative activation or coating treatment.


TY-423 has high phosphorus and nitrogen content, P-N system produces synergistic effect, good flame retardant, and high thermal stability. With low water solubility, PH value close to neutral, excellent dispersion performance, good chemical stability, good compatibility, it is low toxicity and low smoke, safe and efficient inorganic phosphorus flame retardant.


TY-423 can be used in conjunction with carbon forming agent and foaming agent, and can be used in the flame retardant treatment of PE/PP/PU and other thermoplastic materials, oxygen-containing group materials or high-grade expansion fire retardant coatings, with better flame retardant efficiency.
