Product Description

Flame Retardant Rigid Polyurethane Foam Class B1 With A Phosphorus-Nitrogen Intumescent Flame Retardant


Rigid polyurethane foam (RPUF) has been widely used as insulationg materials, construction panel sandwich structures, cushions of furniture and packaging materials in  automobiles, transportation, energy storage and electromagnetic interference shielding fields due to its high machnical propeertiees, insulated properties. 


The improvement of thee flame retardancy of RPUF has curreently been an important subject among the developments of new polymer foam materials. The  environmentally-friendly flame retardant additives with good flame retardancy are particularly needed. In recent years, the phosphorus-nitrogen intumescent flame retardant(IFR) have been widely used as halogen-free additives because thy provide excellent fire protection with less smoke and lower toxicity. 


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) ≥47%
N content (w/w) ≥8%
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.
