TF-PU501 is a flame retardant product specially developed for PU rigid foam. Its gray powder is halogen-free and heavy metal-free, with a neutral PH value, water resistance, good smoke suppression effect, and high flame retardant efficiency.
if customers have no requirementof particle sizes and colors,TF-pu501 is very suitable for rigid Pu for flame retardant , providing an excellent fire protection solution for PU materials that are widely used in our lives. In modern society, the widespread use of PU materials has become a necessity in various fields. Whether in the furniture, construction, transportation or aerospace industries, fire protection requirements are required.
Specification | TF-PU501 |
Appearance | Gray powder |
P2O5 content (w/w) | ≥41% |

1. Gray powder, expands when heated, efficient in smoke suppression.
2. Excellent water resistance, not easy to precipitate, high flame retardant efficiency.
3. 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.
TF-PU501 can be used solely in flameproof treatment or used together with TEP for rigid polyurethane foam. When singly added 9%, it can reach OI request of UL94 V-0 . When singly added 15%, it can achieve classification B1 for burning behavior of building materials with GB / T 8624-2012.
What's more , the smoke density of foam is less than 100.
