Product Description

PU Flame Retardant APP Flame Retardant Halogen Free Fire Retardant For PU Wheel And Roller

 

Rigid Polyurethane foam (RPUF)  is recognized as the best thermal insulation material in the world , but the unflame-retardant polyurethane foam often causes fire . 

 

Rigid Polyurethane Foam has excellent physical and mechanical properties , electrical properties , acoustic properties and chemical corrosion resistance , and has a strong adhesion with a variety of materials . As a result , it is widely used as thermal insulation materials for chemical pipes , refrigeration equipment , transportation equipment and buildings . However , the oxygen index of unflame-retardant polyurethane hard foam is generally lower than 19 , which belongs to flammable materials and releases HCN , CO and other toxic gases in the combustion process . 

 

Ammonium polyphosphate (TF-PU501) is a halogen free flame retardant which can be used for RPUF.

 

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.

 

Application: TF-PU501 is used solely in flameproof treatment for rigid polyurethane foam. UL94-V0 and GB / T 8624-2012 B1 can be achieved when addition volume of APP more than 15% .   B2 -9%.
