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 :
|P2O5 content (w/w)||≥47%|
|N content (w/w)||≥8%|
|pH value (10% aqueous suspension, at 25ºC)||6.5-7.5|
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%.
