Product Description

Halogen Free Flame Retardant in Rigid Foam for Heat Insulator Materials



Model No.: TF-PU501


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

Technical Data Sheet / Specification :

Specification TF-PU501
Appearance Gray powder
P2O5 content (w/w) ≥41%
N content (w/w) ≥6.5%
pH value (10% aqueous suspension, at 25ºC) 6.5-7.5
Moisture (w/w) ≤0.5%


Characteristics :
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.


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, shelf life two years.
