Cas No:68333-79-9

Product description:

TY-423 is a long-chain crystal phase II ammonium polyphosphate(n≥ 1000).

It has a higher thermal stability and lower water solubility than crystal phase II Ammonium Polyphosphate.

TY-423 is an environmentally friendly halogen free flame retardant, which develops its effectiveness through phosphorus / nitrogen synergism and also can be compatible with other polymers. It is usually used with charring agent and foaming agent to protect the polymer through its heat-insulating effect.


It can be used together with carbon-forming agent and forming agent, and be applied in fire retardant treatment, such as on PE/PP/PU…thermoplastic materials, oxygen containing group material and high-grade expansive fire retardant coating, it has good fire retardant efficiency.
