solid composite halogen-free phosphorus-nitrogen containing
intumescent flame retardant
TF-PU501 is solid composite halogen-free phosphorus-nitrogen
containing intumescent flame retardant, it acts both in the
phase and the gas phase.
Technical Data Sheet / Specification :
|P2O5 content (w/w)||≥41%|
|N content (w/w)||≥6.5%|
|pH value (10% aqueous suspension, at 25ºC)||6.5-7.5|
1. Gray powder, expands when heated, efficient in smoke
2. Excellent water resistance, not easy to precipitate, high flame
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.
Application: 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.
Packing : 25kg/bag, 22mt/20’fcl without pallets, 18mt/20’fcl with pallets.
Other packing as request.
Storage: in dry and cool place, keeping out of moisture and sunshine, min.
shelf life one year.
