Product Description


Rigid Foam Fireproof Using Halogen Free Flame Retardant APP Base


TF-PU501 is solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant, it acts both in the condensed phase and the gas phase.




1. Gray powder,

2. expands when heated,

3. efficient in smoke suppression.

4. Excellent water resistance, not easy to precipitate,

5. high flame retardant efficiency.
6. Halogen-free and none heavy metal ions. pH value is neutral, safe and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary.




Appearance                                                                                     Gray powder
